Amplifier Research 200T4G18, Operating And Service Manual

Page: 11 / 60

1. DESCRIPTION AND SPECIFICATIONS
This manual provides operating, interfacing and selected service information pertinent to Amplifier
Research Model 20T4G18 Broadband Microwave Amplifier. The Model 20T4G18 is a 20 watt C/I/J
band traveling-wave tube amplifier (TWTA).
1.1 TWTA DESCRIPTION
The amplifier uses a broadband micro- traveling-wavetube (TWT) to provide 20 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 5.25 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 99-260 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 upper and lower panels of the rack mountable amplifier are interlocked to reduce the likelihood of
accidental contact with high voltage.
