1. DESCRIPTION AND SPECIFICATIONS
This manual provides operating, interfacing and selected service information pertinent to AR
RF/Microwave Instrumentation Model 500T2G8 Broadband Microwave Amplifier. The Model
500T2G8 is a 500 watt S/C band traveling-wave tube amplifier (TWTA). This manual supports models
offering three phase and single phase operation, as well models offering additional special features.
Refer to the model specification sheet to determine the applicable features of this unit.
1.1 TWTA DESCRIPTION
The amplifier uses a broadband traveling-wave tube (TWT) to provide 500 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. The front panel
of the rack mountable amplifier is 8.75 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 208 volts (±10%) 50/60 Hz., three-phase, five-wire or alternatively depending upon Model
190-260VAC single-phase 50/60 Hz. An efficient switching power supply design provides minimum power
consumption. In addition, the dual collector TWT is designed to minimize prime power consumption at low
RF output levels. 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 enclosure are interlocked to reduce the likelihood of accidental
contact with high voltage.
