COMTECH XICOM – OUTDOOR, XTD-500DBS, AC-Powered, Air-Cooled, DBS-Band, 500-Watt SSPA

Description

XICOM – XTD-500DBS, High Power 500W, Ku-Band, GaN SATCOM SSPA
Xicom Products D-500DBS are compact self-contained, antenna mountable power amplifiers 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.

The XTD-500DBS may be configured for single thread, redundant or phase-combined operation. An optional lineariser is available to allow increased transient power while meeting spectral regrowth requirements.
Xicom is the world leader in innovative TWTA design. Xicom’s outdoor antenna mounted TWTAs are known worldwide for their reliable operation and long life. Acclaimed for their compact and highly efficient design, Xicom’s antenna-mount amplifiers dramatically reduce both installation and operation costs. Products span C-band to V-band with high power and efficiency.
