The Xicom XTD-750DBS series are compact self-contained, antenna mountable power amplifier
designed for low cost installation and long life. The design eliminates
the need for an amplifier shelter as well as a long waveguide run between the amplifier
and the antenna feed horn. RF harmonic filters, cooling, and monitoring
& control systems are all self-contained within the HPA. These features provide high
reliability, low maintenance costs, and low replacement costs.
Peak Power or CW
No Shelter required
Short Waveguide Run
Power Factor Correction
The amplifier incorporates a high efficiency multi-stage collector TWT. Some of the
benefits are: reduced prime power consumption, lower internal operating temperatures,
and reliability enhancement. These benefits are obtained for both the linear and saturated
modes of operation.
The units are available with either CW tubes or peak power tubes. CW amplifiers
are used when the operator desires maximum transmit power, while peak power HPAs are
selected for users that operate only in the linear range. An optional linearizer is
available to allow increased transmit power while meeting spectral regrowth requirements.
A complete serial monitoring and control system is built into the unit. The amplifiers
may be configured for single thread, redundant or phase-combined operation. It can be
configured to control one or two switches.
A remote external controller is available to operate the HPA from user selected location.
Mounting brackets can be supplied to mount the HPA to most popular antennas.
