Comtech 250W Peak V-Band Liquid-Cooled Antenna Mount High Power Amplifier

The XTDL-250QV2 series are compact, self contained antenna mount power amplifiers designed for low cost installation and long life. The unit is liquid cooled instead of air-cooled, offering users ambient noise reduction, reduced heat load in hubs, and superior gain stability over temperature. Air conditioning in the hub is also simplified or eliminated.

The XTDL-250QV2 family features high RF efficiency which enables a smaller, lighter amplifier with the ability to operate at up to 60 deg C ambient temperatures.

Comtech Xicom has developed proprietary features to improve performance and life including an automatic bias control system which extends TWT life by maintaining constant beam current over time and a precise system for matching linearizer performance to a specific tube over a wide range of operating conditions maximizing useable linear power

Optional integrated block upconverters (BUC) are available. They can be ordered with an integral 10 MHz reference module for independent operation or with external 10 MHz input for phase lock to GPS or other system clocks.

The amplifier is equipped with an internal 1:1 switch control capable of driving an input and output switch for redundancy. Rack mountable controllers are also available.
