SAFETY FIRST

GENERAL

The operation of electronic equipment involves the use of voltages which may present a hazard to the maintainer. Although every reasonable practicable safety precaution has been incorporated in this equipment, the following rules should be observed.

1. The power should be disconnected and any high voltage capacitors tested to ensure discharge is complete before handling the interior of equipment units.

2. If it is necessary to make measurements on equipment with power applied it is essential that two persons are present, both fully conversant with the equipment, and capable of rendering first aid.

A means of isolating the equipment from the mains must be within easy reach.

3. The equipment should never be operated without being connected to earth and to the supply in the approved manner outlined in the installation chapter of the handbook.

4. All protective covers, safety devices and interlocks should be in place and fully serviceable at all times, during normal operation.

MECHANICAL SAFETY

To ensure safe handling every effort is made to eliminate sharp edges, burrs and protrusions from equipment on both external and internal faces.

Racks and cabinets, when properly installed, are designed to be stable and safe from toppling when any unit is extended on runners, and also upon removal of a lower heavy unit.

When removing units from a rack or cabinet, cables must be disconnected and a flat surface large enough to support the entire unit placed as close as possible, with suitable protection for any projecting items.

Careful note should be made of limits of extraction or stops when starting withdrawal and the marked lifting points or handles used.

No attempt should be made to transfer equipment weighing more than 13kg (28lb) to a supporting surface without an assistant, since even comparatively light units are frequently too large for a safe two hand grasp.

CHEMICAL SAFETY

Where the use of potentially toxic material is unavoidable dangerous material is clearly marked.

Warnings published in local Safety Instructions and Regulations and Manufacturers’ data sheets specify the precautions to be taken when handling hazardous material and the remedial action to be taken in the event of accidental contact with the material.

DISPOSAL OF HAZARDOUS MATERIAL

The disposal of hazardous material is to be carried out in accordance with the latest local Safety Orders and Regulations.

For environmental protection, batteries and electrical boards must be disposed of in accordance with Waste Electrical and Electronic Equipment (WEEE) 2002/96/EC regulations through licensed disposal operators.

It is advised that all condemned equipment should be passed through internal corporate processes for appropriate disposal.

INTRODUCTION

1. The PA8100H series HF Power Amplifier ((referred to in this Handbook as the Power Amplifier or PA) units forms part of an integrated communication system, being installed together with a HF Software Defined Radio (HF SDR), a 6000 series Exciter or a third party Exciter.

2. The PA8109H 1 kW PA unit accepts Radio Frequency (RF) input from the associated Exciter and amplifies it linearly to give 1 kW Peak Envelope Power (PEP) or Continuous Wave (CW) RF output.

3. The PA8105H 500 W PA accepts RF input from the associated Exciter and gives 500 W PEP or CW RF output.

4. The control functions of each PA can all be accessed remotely by the Exciter via dedicated control lines and a serial data link. It can also provide status information and carry out Built In Test (BIT) when requested.

5. The PAs employs an Automatic Level Control (ALC) scheme that minimises output signal overshoot, automatically providing maximum available power into any passive load.

6. Each PA is protected against internal and external faults and indicates to the Exciter when it has detected a fault. There is a diagnostic port on the front panel of each unit for local interrogation to check the operational status of the unit and to aid diagnosis of faults.

7. Both PA variants in the series have a high degree of modularity for maximum reliability and ease of maintenance. Each unit has both low pass and high pass filters for enhanced co-site performance.

8. Electrical power for each PA is 48 VDC supply and a 12 V auxiliary supply. The 48 VDC supply is derived from the primary source in an external Power Supply Unit (PSU).

9. The 1 kW PA variant contains four PA modules capable of delivering up to 400 W each. These are combined to give a total power output of up to 1 kW. Operation is possible with up to three of the four 400 W PA modules not functioning. An internal switched attenuator allows the output power to be reduced in 1 dB steps to 1 W.

10. The 500 W PA variant contains two PA amplifier modules capable of delivering up to 400 W each.

These are combined to give a total power output of up to 500 W. Operation is possible with the other 400 W PA modules not functioning. An internal switched attenuator allows the output power to be reduced in 1 dB steps to 1 W

11. For ease of maintenance, all Line Replaceable Units (LRUs) in the PAs are interchangeable and can be replaced using standard tools. The LRUs can also be replaced in situ without removing the PA completely from the cabinet. This is achieved by sliding the unit forward on the runners to the locked position.

12. The major LRUs in each PA unit are as follows:

• Control Board Printed Electronic Circuit (PEC) (608820-00SP)

• Pre-Amp/Splitter Module (608819-00SP)

• 400 W PA Module (608821-00SP)

• Four-way Combiner (608824-00SP) [1 kW PA only]

• Two-way Combiner (634917-00SP) [500 W PA only]

• High Pass Filter (608823-00SP)

• Low Pass Filter (608825-00SP)

• RF output PEC (608826-00SP)

Page 1-4 Iss. 6.0

• Connector interface PEC (632920-00SP)

• Display Board PEC (608827-00SP)

• Auxiliary PSU PEC (608818-00SP).

13. The 1 kW PA is designed to fit into a standard 11U 19” cabinet of 800 mm depth and occupies 8U of height, whilst the 500 W PA occupies 6U of height.

14. Forced air is used to cool the PAs by drawing in air at the front of the unit and exhausting it from the rear. The airflow is managed to maintain a safe heat sink temperature, this ensures that the audible noise is kept to the minimum for the prevailing conditions.

Advanced ALC

15. Following an initial tune sequence, each PA employs an ALC system to provide an optimum available power into any passive or a cosite load. The available output power in most cases exceeds that from other amplifiers using traditional load Voltage Standing Wave Ratio (VSWR) output power de-rating methods.

Built In Test

16. Continuous Built-in Test (CBIT) automatically monitors internal conditions to prevent failure of assemblies; fault conditions encountered are immediately reported to the host Exciter or receiver/Exciter.

The PA also performs Power-up Built-in Test (PBIT) and Initiated Built-in Test (IBIT).

Antenna Interface

17. The PA incorporates an integral Antenna Coupling Unit (ACU) control interface as standard. This enables operation into a whip antenna, via an AEA-177 (ACU51) or an AS6000 Loop Aerial or a CA6000 series of Common Aerial Working (CAW) systems. Refer to CAT 4, ‘Software Configuration’ for details of how to set ACU type in Model.Env. Refer to Table 1-1 for the following Handbooks for details of the associated equipment:

Man Aloft Key

18. An external control input is provided for connection to a Man aloft key switch. This input disables the PA bias and inhibits the 48 VDC power supply. This ensures that the PA is locked in the ‘SAFE’ condition while maintenance is carried out on any antenna array or ACU associated with the PA.

Note:

By default the PA is disabled. Man Aloft I/P must be linked to ground if a Man Aloft Key is not used.

Refer to CAT 4, ‘PL7-Amplifier Interface’ for details.

DC Supply

19. The PA is powered by an external PSU with the following supplies:

• Primary supply 48 ±1 VDC o power consumption < 2.9 kW for 500 W PA (CW) o power consumption < 4.8 kW for 1 kW PA (CW)

• Auxiliary 12 V supply for PA / PSU control function.

EQUIPMENT SPECIFICATIONS

RF Characteristics

Frequency Range

20. Output frequency range 1.5 MHz to 30 MHz.

21. Rx frequency range 1.5 MHz to 30 MHz (Functional from 500 kHz to 1.5 MHz).

Power Output

22. The 1 kW PA will, in the absence of co-site interference, produce output power of 1 kW CW or PEP, between 1.5 and 30 MHz, forward power +1/-¾ dB into a load with a VSWR of 1.1:1, with respect to 50 Ω.

23. The 500W PA will, in the absence of co-site interference, produce output power of 500 W CW or PEP, between 1.5 and 30 MHz, forward power +1/-¾ dB into a load with a VSWR of 1.1:1, with respect to 50 Ω.

Note:

The asymmetric output power tolerance is to allow for cable losses in the cabinet.

24. The RF output power variation over full operating range is less than ±1 dB.

External Power Reduction (-3dB) Mode

25. The RF output power can be reduced by a nominal 3 dB when the power protection line is in the active state.

This is frequently used in conjunction with a CAW.

Power Level

26. Each PA power level is adjustable in steps of 1 dB down to 1 W with the following accuracy:

• Relative accuracy of each 1 dB step ± 0.75 dB

• Absolute accuracy:0 – 10 dB ± 1 dB

• 10 – 20 dB ± 1.5 dB

• 20 – 30 dB ± 2 dB.

27. This reduction is controlled via the Exciter control interface.

Co-site Operation

Broadband Co-site

28. When operating with three similar amplifiers into a 4-way CAW system connected to a broad band antenna with a VSWR of 3.5:1, the power output (measured at the transmitter output port) will remain within ±1dB of the nominal power.

Narrowband Co-site

29. The I kW PA will continue to deliver its rated power ± 1dB, measured at its output port, when operating into an ACU with a VSWR of ≤ 1.5:1 with a co-site signal of 100 W present at the victims RF output. The frequencies of the transmitters shall be separated from each other by ≥ 5%.

Page 1-6 Iss. 6.0

Note:

This is equivalent to a victim transmitter with 40 W due to the VSWR and 100 W due to the presence of the co-site signal.

30. The 500 W PA will continue to deliver its rated power ± 1dB, measured at its output port, when operating into an ACU with a VSWR of ≤ 1.5:1 with a co-site signal of 50 W present at the victims RF output.

The frequencies of the transmitters shall be separated from each other by ≥ 5%.

Note:

This is equivalent to a victim transmitter with 20 W due to the VSWR and 50 W due to the presence of the co-site signal.

Operation into adverse VSWR

31. The PA will not be damaged or trip by operation into a load with a VSWR greater than 2:1.

32. When operating into a load with a VSWR greater than 2:1, the PA will continue to operate at a reduced forward power greater than 1.3 / VSWR x 100% of the full rated power. (MIL-STD-188-141B, Para 5.3.7).

Inter-modulation Products (IPs)

Forward Inter-modulation Products

33. With the PA providing any power up to its nominal output PEP by a signal comprising two equal tones, the IPs produced will be at least 32 dB below either tone (38 dB below PEP). (Measured using a 50 Ω load of better than 1.1:1 VSWR, Source IMD level of –60 dBt or better and two equal tones separated by 600 Hz.)

34. When driven from a typical RF source e.g. HF SDR, with an IMD performance of better than –45 dBt the IPs produced by the amplifier are better than –30 dB below tone (-36 dB below PEP).

Reverse (Backdoor) Inter-modulation Products

35. With the amplifier working into a 50 Ω load with a VSWR <1.1:1, an unwanted signal of -30 dB wrt the wanted transmission and at 5 % frequency separation, will produce inter-modulation products of better than 45 dB below the wanted signal.

Note:

These figures represent the worst case scenario, i.e. two transmitters operating in the same PA filter band, producing third order inter-modulation products that also lie within the filter band.

Iss. 6.0 Page 1-7

36. When the unwanted signal falls outside the filter stop band (see Table 1-2) the inter-modulation products will be better than 75 dB below the wanted signal.

Modes of Operation

37. The PAs are capable of amplifying any of the following modes:

• Continuous Wave (CW),

• Modulated Carrier Wave (MCW),

• Amplitude Modulation (AM),

• Upper Side Band (USB),

• Lower Side Band (LSB),

• Independent Side Band (ISB),

• Frequency Shift Keying (FSK,

• Link 11 (Tadil-A and STANAG 5511),

• FM Narrow Band.

Harmonics

38. All harmonics produced by the PAs are better than -63 dBc (typically better than –70 dBc) when operating at nominal output power into a 50 Ω load with a VSWR of ≤ 1.1:1.

Spurious Outputs

39. Hum side-bands are ≤55 dB below PEP (at full rated power). All other spurious are:

• < -60 dBc at frequencies <5 % off tune

• < -80 dBc at frequencies >5 % off tune, below PEP (at full rated power).

Page 1-8 Iss. 6.0

Noise Power (at full rated output)

40. The Noise power at the RF output port is <108 dBm/Hz over the frequency range 1.5 – 30 MHz. This equates to a wideband (±5%) noise level of better than –165 dBc/Hz when driven from an Exciter with a noise performance of better than –168 dBc/Hz.

Tuning Power

41. Following a request from an ACU or Loop Antenna each PA will provide a tuning signal of 12 W ± 1 dB to allow the ACU or Loop Antenna to be tuned.

Input Protection

42. The PA input is capable of withstanding a drive level of 23 dBm; the input is protected against an input power levels up to 33 dBm.

Transmitter/Receiver Isolation

43. The isolation between the RF (amplifier) output and the RF (receiver) output is >75 dB when the amplifier is switched to the Transmit mode.

Receive Path Loss

44. When the amplifier is switched to the Receive mode the loss between the RF Output socket (SK5) and the Receiver output socket (SK6) is <0.5 dB within the frequency range 0.5 – 30MHz.

RF inhibit / Radio Silence

45. When either the RF inhibit or radio silence lines are in the active state the RF output will be reduced by >60 dB relative to PEP.

Phase Matching

46. The phase matching between any complete PA assemblies will be better than 20 degrees. This ensures that when used in coherent mode in a CAW system, the losses due to phase imbalance are minimal.

Control Characteristics

Initialisation, Responses to stimuli etc.

47. The amplifier will be available for use within 90 seconds of power being applied. The power up sequence includes an extensive PBIT.

48. Any faults logged within the modules are reported to the Exciter and are also available on the PA’s Diagnostic Port.

49. At Power Up or following the loss of primary power to the PA, the PA will recover to the last known state when the supply is restored.

Protection

Temperature

50. The PA will protect itself against internal overheat in any monitored LRU by reducing forward power output. If this fails to moderate the temperature a trip will operate and shut the system down in order to protect the unit from damage.

Voltage Standing Wave Radio

51. The PA monitors forward and reverse power levels and adjusts the output power to maintain it within safe limits.

Iss. 6.0 Page 1-9

Co-site

52. Under normal operating conditions a closed loop system monitors the reverse power, PA device peak current - voltage and heat sink temperature. If any of these parameters exceed safe operating limits the PA automatically adjusts the forward power to prevent damage, without causing an interruption to the transmission.

53. Under extreme conditions, e.g. blocked air duct or a shorted cable in the antenna feed system, hardware trips protect the unit.

Power Amplifier Tuning Time

Operation without ACU/Loop Antenna

54. The channel change time of the PA is < 250 ms for a pre-tuned channel (measured from the command to change channel to the assertion of the READY signal). It is not possible to change channel whilst the unit is in the BUSY state.

55. The channel tuning time of the PA is < 1.5 s (measured from the command to change frequency to the assertion of the READY signal).

Operation with ACU/Loop Antenna

56. The PA will provide the tuning command to the ACU/Loop in < 200 ms after the receipt of the tune command from the radio.

Key-up / Key-down Switching Times

57. Change-over time between Key-up / Key-down (transmit and receive modes) is:

58. Key-down switching time < 10 ms from keying-on for the amplifier to achieve 90% of full specified output power.

59. Key-up switching time < 10 ms.

Module Failure

60. The PAs will continue to operate at reduced power in the event of an amplifier module failure.

Pre-set Channels

61. 1000 pre-set channels are available. For each of these channels the following parameters are stored in non-volatile memory:

• Frequency

• Mode

• Transmitter (Tx) Power

• Calibration data

• Transmitter status flags

• Channel Data Checksum.

OPERATION

Controls

1. There are no operator controls on the front panel of either PA8109H 1 kW Power Amplifier or PA8105H 500 W Power Amplifier (both variants referred to in this Handbook as the Power Amplifiers or PAs).

2. Both PAs can be controlled either via the High Frequency Software Defined Radio (HF SDR) from the Local Control Terminal (LCT) (refer to handbook HB1554), or via the 6000 Series Exciter from the CU6000 Control Unit (refer to handbooks HB 1503, HB1446 or HB1447).

Indicators

3. Refer to Figure 2-1 for PA8109H 1 kW PA Front Panel Indicators.

FIGURE 2-1 PA8109H 1 KW PA FRONT PANEL INDICATORS

4. Refer to Figure 2-2 for PA8105H 500 W PA Front Panel Indicators.

FIGURE 2-2 PA8105H 500 W PA FRONT PANEL INDICATORS

5. The following indicators are fitted on each PA front panel.

13. The reverse power bar graph is graduated 0 – 150 W.

14. The reverse power bar graph is green up to a power of approximately 45 W and amber for reverse powers in the range 45 – 150 W, to show that a significant amount of reflected or cosite power is present on the amplifier’s output.

Status Indicators

15. There are four status indicators on each PA front panel labelled as Power, Busy, Ready and Fault.

Power

16. The ‘Power’ indicator has four states:

• Off – no DC power supply applied to the PA

• Red – external DC auxiliary supply applied but primary 48 V supply inhibited at external PSU

• Amber – external DC auxiliary supply and 48 V supply applied, PA in a standby state (no 48 V to

400 W PA modules)

• Green – external DC power and 48 V supply applied, PA in operational state (48 V applied to 400

W PA modules).

Busy, Ready and Fault

17. The ‘Busy’, ‘Ready’ and ‘Fault’ indicators are illuminated in the following combinations to show the PAs status (refer to Table 2-1).

TABLE 2-1 POWER AMPLIFIER STATUS INDICATORS

Status Busy Ready Fault

Power Amplifier Un-tuned Off Off Off

Tuned and ready for operation Off Green Off

Tuning or running PBIT / IBIT Amber Off Off

Transmitting Amber Green Off

Iss. 6.0 Page 2-5

18. The ‘Fault’ indicator is illuminated RED to show a PA fault. When the ‘Fault’ indicator is illuminated the cause of the fault can be determined by viewing the fault log. Refer to the Error Codes section in this manual HB608690-00, Category 5 to determine the possible cause of the failure.
