The Xicom XTRD-2000X digital rack-mount amplifier is designed for fixed and mobile uplink
application. The high efficiency traveling wave tube amplifier includes RF gain control,
a solid state pre-amplifier, RF filter, cooling, and a monitor & control (M&C) system.
An integrated X-Band linearizer is available. The dual-drawer amplifier conserves rack
space and occupies only 19.25 inches (11 rack units) of a standard 19 inch rack cabinet.
A complete 1:1 or 1:2 redundant TWTA system, including a redundant controller, can be mounted
in a single rack.
Digital Display and
The XTRD-2000X features a menu-driven front panel display and RS-232 & RS-422/RS-485
serial port interfaces for complete remote control. Gain control
is set by the front panel manual control or by computer commands sent via the remote
The unit incorporates a high efficiency, multi-stage depressed collector TWT.
Reliability is enhanced because both prime power consumption and internal operating
temperatures are reduced for the linear and saturated modes of operation. The high
frequency resonant conversion power supply is highly efficient and allows for quick
recovery from prime power outages. Depending upon user requirements, the XTRD-2000X
can be configured for single-thread, redundant, or phase combined operation.
