The AA-618G-300-GT from Advanced Amplifiers is TWT Amplifier that operates from 6 to 18 GHz. It delivers an output power of more than 250 W (54 dBm) with a gain of 54 dB. This amplifier generates output power with a pulse width from 0.1 μs to CW with a rise/fall time of less than 15 ns and a pulse jitter of ±2 ns. It has spurious emissions of -60 dBc (250 MHz and above) and has a gain stability of 0.25 dB/24 hours. The amplifier is equipped with built-in protection circuits and has extensive internal monitoring. It is available in a 5U chassis with N-type (female) input connector and WRD-650 output waveguide interface. This TWT amplifier also has versatile control interfaces which include RS-232 and optional IEEE-488 and RJ-45 Ethernet interfaces. It requires an AC supply.
