XTRD-400C C-Band High Power Rack Mount Amplifiers
The Xicom XTRD-400C is a highly efficient rack mountable traveling wave tube amplifier (TWTA) designed for fixed and mobile uplink applications.
The unit includes RF gain control, a solid state pre-amplifier, RF filters, cooling, and monitoring and control (M&C) systems.
Rack space is conserved because the amplifier occupies only 3 rack units (5¼ inches) of a standard 19-inch rack cabinet. Nominal weight is 56 pounds.

- Power Factor Correction
- Digital Display & Control Interface
- High Efficiency
The unit features a menu driven front panel display and RS-232/422/485 serial port interfaces for complete computer control. RF, traveling wave tube, and default parameters are easily monitored on the four line front panel display.
Gain control is provided via the front panel or through the serial interface.
The XTRD-400C incorporates high efficiency, dual stage collector TWTs. Reliability is enhanced because both prime power consumption and internal operating temperatures are reduced for both the linear and saturated modes of operation.
Power factor correction circuitry is also included which minimizes line current distortion and reduces the required Volt- Amps input.
The automatic features of the high frequency resonant conversion power supply include quick recovery from prime power outages and mulitiple helix fault resets (three fault cycles.)
Depending upon user requirements these amplifiers can be configured for either single thread or redundant system operation.
