Product Overview

Rent Amplifier Research 250S1G2z5A Microwave Amplifier (Call for Availability):


The Amplifier Research 250S1G2z5A is a self-contained, air-cooled, broadband, completely solid state amplifier designed for applications where instantaneous bandwidth, high gain and linearity are required. Housed in a single equipment rack, the 250S1G2z5A provides readily available RF power for typical applications, such as RF susceptibility testing, antenna and component testing, watt meter calibration, and as a driver for frequency multipliers and higher power amplifiers. A safety interlock can be implemented via a rear panel connector. 


The 250S1G2z5A, when used with a sweep generator, will provide a minimum of 250 watts of RF power. Included is a front panel gain control which permits the operator to conveniently set the desired output level. The 250S1G2z5A 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.


The Amplifier Research 250S1G2z5A 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 and RF output level protection.


All amplifier control functions and status indications are available remotely in GPIB/IEEE- 488 format, RS232 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 keylock on the front panel of the amplifier.


The low level of spurious signals and linearity of the Amplifier Research 250S1G2z5A 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, WCDMA, TDMA, GSM etc. It is also suitable for EMC Test applications where undistorted modulation envelopes are desired.
