Xicom XTRD-2000X 2250W X-Band Rack Mount TWTA
Xicom XTRD-2000X Digital Rack-mount Amplifiers
are designed for fixed and mobile uplink
applications and occupy only 11 rack units
while providing RF output of 2000 Watts.
XTRD-2000X Features
- 2250 Watts
- Compact Size
- High Efficiency
- Digital Display and
Control Interface
- Power Factor
Correction
- Linearizer Option
These high efficiency traveling wave tube
amplifiers include RF gain control, a solid
state pre-amplifier, RF filters, cooling, and
monitor & control (M&C) systems. 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.
The unit 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 interface(s).
The units incorporate high efficiency,
multi-stage depressed collector TWTs.
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
high power amplifiers can be configured for
single-thread, redundant, or phase combined
operation.
