Amplifier Research 20T4G18A

20Watt CW, 4.2-18GHz TWT Microwave Amplifier

Self-contained, air-cooled, broadband traveling wave
tube microwave amplifier designed for applications where
instantaneous bandwidth and high gain are required. A reliable 20 watt TWT
provides a conservative 20 watts minimum at the amplifier output connector.

Never operate the TWT Amplifier without a matched output load rated for at
least 50 watts, continuous.
This could result in damage to the tubes.

Standard features include:
Built-in IEEE-488 (GPIB) interface; 0dBm input;
VSWR protection; gain control, RF output sample port,
Plus monitoring of TWT helix current: cathode voltage; collector voltage;
Heater current; heater voltage; baseplate temperature and cabinet temperature

Power (fundamental), CW, @ output connector
