1. DESCRIPTION AND SPECIFICATIONS
This manual provides operating, interfacing and selected service information pertinent to the AR
Worldwide Model 40T26G40A Broadband Microwave Amplifier. The Model 40T26G40A is a 40-watt
Ka-band Traveling-Wave Tube Amplifier (TWTA). Refer to the Model Configurations on the data
sheet to determine the applicable features of this unit.
1.1 TWTA DESCRIPTION
The amplifier uses a broadband millimeter-wave traveling-wave tube (TWT) to provide 40 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 for 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.
