Product Overview

Rent Amplifier Research 25S1G6 Microwave Amplifier (Call for Availability):


The Amplifier Research 25S1G6 is a solid-state, Class A design, selfcontained, air-cooled, broadband amplifier designed for applications where instantaneous bandwidth and high gain are required. Housed in a sfylish contemporary cabinet, the unit is designed for benchtop use, but can be removed from the ca binet for immediate equipment rack mounting. The 25S1G6, when used with a sweep generator, will provide a minimum of 25 watts of RF power. Included is a front panel gain control which permits the operator to conveniently set the desired output level. The 25S1G6 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 digital display on the front panel to indicate the operate status and fault conditions when an over-temperature or power supply fault has occurred. The unit can be returned to operate when the condition has been cleared. The 2551 G6 includes digital control for both local and indications are available remotely in GPIB/IEEE-488 format, RS-232 hardwire and fiber optic, USB, and Ethernet. The bus interface connector is located on the back panel and positive control of local or remote operation is assured by a Local/ Remote switch on the front panel of the amplifier.
