The XTD-250QV from Comtech Xicom Technology is a V-Band Antenna Mount High Power TWT Amplifier that operates from 47.2 to 51.4 GHz. The amplifier provides up to 250 Watts of peak power with a gain of over 60 dB. A pre-distortion linearizer is also included to optimize linear power at the HPA (high-power amplifier) flange. The amplifier is ideal for high throughput satellite (HTS) gateway applications.
The XTD-250QV provides several methods of tube protection including output power monitoring. It is available in multiple configurations with redundancy and preamplifiers with fixed or variable gain. An external remote controller is available to operate the HPA from a user-selected location.
