Description
XICOM – XTD-400C, High Power 400W, C-Band, GaN SATCOM TWT’s
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, internal LO reference, extensive data logging, easy-to-use web-based GUI, ethernet SNMP (v1 or v3), and a wide range of available power combined and redundancy systems. The XTD-400 is a compact self contained antenna mountable high power amplifier (HPA) designed for low cost installation and long life. The outdoor design eliminates the need for an amplifier shelter as well as a long waveguide run between the amplifier and the antenna feed horn. RF filters, cooling, and monitoring & control (M&C) systems are all self contained within the HPA. These features provide high reliability, low maintenance costs, and low replacement costs.
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.
