Overview
Amplifier Research 200T4G8 Description:
The Amplifier Research Model 200T4G8 is a self contained, forced air cooled, broadband traveling wave tube (TWT) microwave amplifier designed for applications where instantaneous bandwidth and high gain are required.
A reliable 250 watt TWT provides a conservative 200 watts minimum at the amplifier output connector. Stated power specifications are at the funda- mental frequency.
The amplifier's front panel digital display shows forward and reflected output plus exten- sive 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 in- clude a built-in IEEE-488 (GPIB) interface, 0 dBm input, VSWR protection, gain control, RF output sample port, plus monitoring of TWT helix current, cathode voltage, collector volt- age, 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.
Housed in a stylish contemporary cabinet, this unit is designed for benchtop use but can be removed from cabinet for rack mounting. The Model 200T4G8 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.
