Amplifier Research 125S1G4M3-BC Microwave Amplifier 0.7GHz to 4.2GHz, 125 Watts CW

The Amplifier Research 125S1G4M3-BC is a portable, selfcontained, air-cooled, broadband, completely solid-state amplifier designed for applications where instantaneous bandwidth, high gain and linearity are required. Push-pull circuitry is utilized in all high power stages in the interest of lowering distortion and improving stability. The Model 125S1G4, when used with a sweep generator, will provide a minimum of 125 watts of RF power.

The Model 125S1G4 is equipped with a Digital Control Panel (DCP) which provides both local and remote control of the amplifier. The DCP uses a color LCD touch screen and a single rotary knob to offer status reporting and control capability. The display provides Forward Power and Reflected Power values plus amplifier status. Special features include a gain control, internal automatic level control (ALC) with front panel control at the ALC threshold, and RF output level protection.

All amplifier control functions and status indications are available remotely in GPIB/IEEE488 format, RS232 hardwire and fiber optic, USB and Ethernet. Remote interface connectors are located on the back panel and local or remote operation is determined by a keylock switch on the front panel of the amplifier.

The low level of spurious signals and linearity of the Model 125S1G4 make it ideal for use as a driver amplifier in testing wireless and communication components and subsystems. It can be used as a test instrument covering multiple frequency bands and is suitable for a variety of communication technologies such as CDMA, W-CDMA, TDMA, GSM etc. It is also suitable for EMC Test applications where undistorted modulation envelopes are desired.
