QUESTIONS AND ANSWERS

AMENDMENT 0002

Section B. Supplies and Services

1) Question: What is the desired monthly delivery rate Yr1-5 for 1611AS474 and 1611AS479 amplifiers?

ANSWER: Minimum units is 3 per month

2) Question: Are there any current areas of concern with the current MPMs? Are there any particular areas of the technical specifications or reliability in which ATSO would like particular emphasis on?

ANSWER: No areas of concern with the current MPM.

3) Question: 3.3.7 Small Signal Gain/3.3.8 Gain at Rated Power: Gain compression at rated power is expected to be between 12-18dB. Should vendors assume that gain at rated power is more important than gain window?

ANSWER: Small signal gain is more important. The small signal gain shall be between 55 to 65 decibels (dB) from 6 to 16 GHz and 50 to 65 dB from >16 to 18 GHz band. This is in section 3.3.7

4) Question: 3.5.4 Bonding: Can an electrically conductive bonding material to attach RF devices to carriers and assemblies be used?

ANSWER: Mechanically bonding through fasteners is essential with electrically conductive bonding material being allowed as a secondary source of attachment. Welding does not require mechanical fastening.

5) Question: 3.5.5 Shelf Life: What is the requirement in terms of years?

ANSWER: The Unit shall be designed to function and operate following a storage period of 5 years.

6) Question: 3.5.7 Mean Time Between Failures: Should vendors assume that that the analysis is to be conducted per MIL-HDBK-217, Notice 2?

ANSWER: Yes

7) Question: 3.5.9 Operating Environment: Clarification on the second bullet. Should vendors assume that the assembly will not be conduction cooled at the baseplate and heat removal will rely on heat being dissipated internally and forced air cooling?

ANSWER: Yes, that is correct. Heat removal will rely on heat being dissipated internally from the amplifier fan.

8) Question: 3.7.3.2.1 Acceptance Operating Temperature Test: Dwell time is significant at temperature extremes (1hr). Could this time be reduced if shown by measurement and/or analysis that internal temperature stabilizes well prior to 1 hr?

ANSWER: No. Need to ensure the device can operate at rated power and temperatures for 1 hour minimum. Actual operational time can be longer than this.

9) Question: Is there flexibility in movement of the RF and DC connectors provided they stay on the same face of the assembly?

ANSWER: No. RF and DC connectors must stay in current location. Hardlines attach to these connectors in some applications.

10) Question: Sheet 2, Zone B1: Overall height of assembly not shown. Dimension of 2.43+/-.060 is dimensioned to the bottom of the cover.

ANSWER: The overall height is 2.50 +/-.060

11) Question: Sheet 2 Zones B/C7: Assumption is that the RF and DC connectors are connected via cables. Current location tolerance on these connectors is +/-.005. Can the locations of the connectors be changed to 2 decimal places and therefore a tolerance of +/-.020?

ANSWER: No. Must stay at current location and tolerance.

12) Question: Sheet 2 Zone B6: Is there a requirement as to how much the connectors should protrude from the face of the assembly?

ANSWER: Yes, the TNC connector with a maximum of 0.5 inch protrusion from the face of the assembly.

13) Question: Sheet 2, Zone B2: Requesting clarification that the 1.25 diameter and .25 max blower extension are in reference to the maximum allowed extension of any part of a fan or blower.

ANSWER: That is correct for the maximum allowed.

14) Question: Is there flexibility in movement of the RF and DC connectors provided they stay on the same face of the assembly?

ANSWER: No. RF and DC connectors must stay in current location. Hardlines attach to these connectors in some applications.

15) Question: Sheet 4 Zones B6/7: Assumption is that the RF and DC connectors are connected via cables. Current location tolerance on these connectors is +/-.005. Can the locations of the connectors be changed to 2 decimal places and therefore a tolerance of +/-.020?

ANSWER: No. Must stay at current location and tolerance.

16) Question: Sheet 4, Zone B2: Requesting clarification that the 1.11 diameter and .23 dimension are in reference to the maximum allowed extension of any part of a fan or blower.

ANSWER: This is correct.

17) Question: Sheet 5, Zone C6: Required Power and Control Connector protrusion not shown.

ANSWER: The power and control connector protrusion dimension is not shown because it does not protrude past the maximum envelope of the amplifier

18) Question: Sheet 5, Zone C2: Is there flexibility for movement of the blower/fan?

ANSWER: No.

AMENDMENT 0001

1) Question: Can an extension to the acceptance of questions be extended to 23 May 2019?

ANSWER: Yes. The amendment will extend the due date for questions until 05 Jun 2019

2) Question: Looking through the drawings and cant' figure if it's an engineering design job or build to print, obviously if it's a build to print there are documents missing. Let me know which?

ANSWER: It is NOT build to print.

3) Question: ATSO First Article Environmental Test Requirements Rev A: Para. 7.8, Figure 7.3 and Table 7.4 Describes an extreme operational environmental test. The simultaneous combination of 40,000 feet altitude and +40 degrees C air temperature for an extended period of operation seems like an unrealistic combination for an airborne application within a pod. Is this a true requirement, and if so please describe the circumstances under which this type of operating environment would exist and if the unit would still need to be operational should such a combination occur.

ANSWER: This is a validated operating environment. We would likely see the +40C at 40,000 feet during flight missions especially at hot testing locations. We can experience pretty high Mach numbers at high altitudes where the air is thin, which is outlined in the MIL-STD 210 guidelines. Yes, the device must remain operational during this temp/altitude combination per the specification.

4) Question: The government document, J1 Performance Based Statement of Work, Paragraph 2.2, refers to two drawings as part of the technical specification. The exact description appears below:

" 2.2 Drawings: (CLINs 0001 – 0004) J-5) 1611AS474-2 Amplifier Radio Frequency AM-7536/ULQ-21(V) Rev K J-6) 1611AS479 Amplifier, Microwave Power Module AM-7559/ULQ-21(V) Rev F”

When we view these drawings, which were provided as part of the technical data package, we see a different revision level marked on the drawing. The revisions appearing on the drawings are:

1611AS474-[ ] Rev K.0T1 and 1611AS479 Rev F.0T1

The revisions of these drawings appear to be in conflict with the PBSOW. Can you clarify which revisions of the drawings are to be proposed, or can you provide new drawings with corrected or updated revisions?

ANSWER: 1611AS474-[ ] Rev K.0T1 and 1611AS479 Rev F.0T1 are the current and correct drawings. The PBSOW has been updated with the current and correct drawings, 1611AS474-[ ] Rev K.0T1 and 1611AS479 Rev F.0T1
