The XTRD-750K is a highly efficient rack mountable traveling wave tube amplifier (TWTA)
designed for test and measurement applications.
The unit includes RF gain control, a solid state pre-amplifier, cooling, and monitoring
and control (M&C) system. Rack space is conserved because the amplifier occupies only 4
rack units (7 inches) of a standard 19 inch rack cabinet.
Nominal weight is 75 pounds.
Compact 7 inch Package
Digital Display & Control
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 4-line front panel display. Gain control is provided via the
front panel or through the serial interface.
The XTRD-750K incorporates high efficiency, multi-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 multiple helix fault resets (three fault cycles.)
Depending upon user requirements, the amplifier can be configured for either single thread
or redundant system operation.
