Amplifier Research 200T4G8 Amplifier, 4 - 8 GHz, 200 Watts
Amplifier Research 200T4G8 Amplifier, 4 - 8 GHz, 200 Watts
The AR-200T4G8 is a self contained, forced air cooled, broadband travelling wave tube (TWT) microwave amplifier designed for applications where instantaneous bandwidth and high gain are required. A reliable 250 watt TWT provides a conservative 200 watts minimum at the amplifier output connector.
