5 W 4.2 GHz Microwave Amplifier. Solid state self-contained air-cooled broadband amplifier designed for applications where instantaneous bandwidth and high gain are required. The AR 5S1G4 when used with a sweep generator will provide a minimum of 5 watts of RF power. Included is a front panel gain control which permits the operator to conveniently set the desired output level. The Amplifier Research 5S1G4 is protected from RF input overdrive by an RF input leveling circuit which controls the RF input level to the RF amplifier first stage when the RF input level is increased above 0 dBm. The RF Amplifier stages are protected from over temperature by removing the DC voltage to them if an over temperature condition occurs due to cooling blockage or fan failure. There is a fault lamp on the rear panel to indicate an over temperature or power supply fault condition.
