Description
XICOM – XTD-1250KHE, High Power 1250W, Ku-Band, GaN SATCOM SSPA
Xicom Products Designed for fixed and transportable terminals needing high power density with high efficiency in challenging environments are flexible, high-performance, AC-powered, antenna-mount outdoor SSPAs/BUCs that offer many features and options including internal L-band BUCs. The XTD-1250 is a compact, self-contained, antenna mountable power amplifier designed for low cost installation and long life. The XTD-1250 design eliminates the need for an amplifier shelter as well as a long waveguide run between the amplifier and antenna feed horn. RF filters, cooling, and monitoring & control (M&C) systems are all self-contained within the High Power Amplifier (HPA). These features provide high reliability, low maintenance costs, and low replacement costs.
The XTD-1250 uses high efficiency, dual-stage collector Traveling Wave Tubes (TWT). Some benefits of this type of tube are: reduced prime power consumption, lower internal operating temperatures, reliability enhancement.
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.
