Product Overview

Rent the Amplifier Research 1500T2G8A TWT Amplifier (Call for Availability):


The Model 1500T2G8A is a self contained, forced air cooled, broadband traveling wave tube (TWT) microwave amplifier designed for applications where instantaneous bandwidth, high gain and high power output are required. Reliable TWT subsystems provide a conservative 1500 watts minimum at the amplifier output connector. Stated power specifications are at fundamental frequency.


The amplifier's front panel digital display shows forward and reflected output plus extensive system status information accessed through a series of menus via soft keys. Status indicators include power on, warm-up, standby, operate, faults, excess reflected power warning and remote. Standard features include a built-in IEEE-488 (GPIB) interface, 0dBm input, VSWR protection, gain control, RF output sample port, plus monitoring of TWT helix current, cathode voltage, collector voltage, heater current, heater voltage, baseplate temperature and cabinet temperature. Modular design of the power supply and RF components allow for easy access and repair. Use of a switching mode power supply results in significant weight reduction.


The rated power is developed by efficiently power combining the outputs from four 500 watts (nominal) microwave amplifiers that are factory matched in gain and phase


The Model 1500T2G8 provides readily available RF power for a variety of applications in Test and Measurement, (including EMC RF susceptibility testing), Industrial and University Research and Development, and Service applications.


Functions ad Specification of the Amplifier Research 1500T2G8A TWT Amplifier Include)


POWER (fundamental), CW, @ OUTPUT CONNECTOR: 

Nominal: 2000 watts

Minimum: 1600 watts from 2.5 – 3.0 GHz,

1700 watts from 3.0 – 7.5 GHz


Linear @ 1 dB Compression: 400 watts minimum


FLATNESS: ±8 dB maximum, equalized for ±6 dB

maximum at rated power


FREQUENCY RESPONSE: 2.5 – 7.5 GHz instantaneously


INPUT FOR RATED OUTPUT: 1.0 milliwatt maximum


GAIN (at maximum setting): 62 dB minimum


GAIN ADJUSTMENT (continuous range): 35 dB minimum


INPUT IMPEDANCE: 50 ohms, VSWR 2.0:1 maximum
