AR 10006031, Operating And Service Manual

Page: 11 / 62

1. DESCRIPTION AND SPECIFICATIONS
This manual provides operating, interfacing and selected service information pertinent to Amplifier
Research Model 200T4G8 Broadband Microwave Amplifier. The Model 200T4G8 is a 200 watt C band
traveling-wave tube amplifier (TWTA).
1.1 TWTA DESCRIPTION
The amplifier uses a 250 watt traveling wave tube (TWT) to provide 200 watts minimum output over the
TWT amplifier's full bandwidth. The amplifier is well suited for susceptibility and general laboratory testing
where instantaneous bandwidth and high gain are required.
The amplifier is completely self-contained and packaged for standard 19-inch rack mounting or bench top
use. The front panel of the rack mountable amplifier is 10.5 inches high, and the overall unit is 25.25 inches
deep, excluding the rear-panel connectors. For bench top use, the amplifier is supplied in an enclosure with
integral carrying handles.
Primary power is 190-260 volts 50-60 Hz., single phase. An efficient switching power supply design
provides minimum power consumption. A fast regulation control loop and a high degree of filtering ensure
performance within specifications over a wide range of operating conditions. The amplifier is fully enclosed,
and the lower panel of the rack mountable amplifier is interlocked to reduce the likelihood of accidental
contact with high voltage.
