Salient description 6000+ watt Power amplifier 80 – 1000 MHz

EPG requires a new self-contained, rugged, reliable, integrated forced air cooled, broadband solid state amplifier (SSA) designed for wide instantaneous bandwidth, high gain, low level spurious signals and harmonics and minimum of 6000 watts at the amplifier output connector.

The amplifier will have RF and hardware protection systems including high VSWR, over-current and voltage protection as well as redundant thermal and airflow sensors to prevent the amplifier from overheating.

The amplifier will be protected from RF input overdrive when the RF input level is increased above max input. The RF amplifier stages will be protected when an over-temperature condition occurs due to cooling blockage or fan failure.

The amplifier will have a front panel digital display that shows forward and reflected output plus extensive system status and self-diagnostic information. Status indicators include power on, warm-up, standby, operate, faults, excess reflected power warning and remote. The amplifier operating parameters are simultaneously available in the amplifier front panel display as well as over the remote bus. Selection switches or keystroke allow you to switch the amplifier to the desired mode of operation for local control if the unit is not being operated remotely.

Amplifier will include a built-in IEEE-488 (GPIB) interface, RS-232 and Ethernet interface.

Amplifier features will include, VSWR protection, gain control, internal automatic level control, forward and reflected RF output sample ports on front panel and cabinet temperature.

Amplifier will be modular in design for easy access and repair of the power supply and RF components.

Amplifier will be housed in a cabinet that include castor wheels, leveling feet and lifting eyes on each cabinet. Each cabinet will be mounted on a rugged base to facilitate use of a forklift to move SSA.

Saturated power: - Swept Power out plots: Frequency versus power out, with associated tabular data, at 0 dBm input.

Linear Power: determine the point of where a 10 dB decrease in input power results in a 9dB decrease in output power for 1dB compression, and a 7dB decrease in output for 3dB compression. The corresponding output power is measured and graphed. This is repeated across the frequency range.

Gain Flatness: Power input level is set to -20dBm. The output power is then read across the frequency range.

Harmonics: Power input level is set to 0 dBm. Using a Spectrum analyzer record the amplitude of fundamental carrier frequency in dBm. The levels of the second and third harmonics are measured in dBm are subtracted from the level of the fundamental. This is repeated across the frequency range.
