Amplifier Research 50W1000B RF Amplifier 1 MHz – 1000 MHz 50W

Description

Amplifier Research 50W1000B is a portable, self-contained, air-cooled, broadband, solid state amplifier designed for applications where instantaneous bandwidth and high gain are required. Push-pull circuitry is utilized in the high power stages to lower distortion and improve stability.

The 50W1000B, when used with an RF sweep generator, will provide a minimum of 50 watts of swept power. Included is a front panel gain control which permits the operator to conveniently set the desired output level.

The 50W1000B is protected from RF input overdrive by limiting diodes and 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 digital display on the front panel to indicate the operate status and fault conditions when an over temperature, power supply, or amplifier fault has occurred. The unit can be returned to operate when the condition has been cleared.

The 50W1000B includes digital control for both local and remote control of the amplifier. This 8-bit RISC microprocessor controlled board provides both IEEE-488 RS-232 control of all amplifier functions.
