XTRD-400K Ku-Band High Power Rack Mount Amplifiers
The Xicom XTRD-400K 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.
XTRD-400K Features
- 400 Watts
- Power Factor Correction
- Digital Display & Control Interface
- High Efficiency
Block Diagram
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-400K 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.
