Comtech Xicom Technology, a subsidiary of Comtech Telecommunications, has been contracted to supply X-band solid state power amplifiers and block-up converters (SSPA/BUC) for transportable military satcom ground systems. The order is valued at over $1 million (€838,000).

X-band is reserved for government satellite service, primarily military applications that require low interference, low rain-fade, and small terminal size, even if data rates are limited. One major challenge is that, unlike other satcom bands, the receive band is adjacent to the transmit band, making it critical that any RF leakage be extremely low to avoid interfering with the receive signal. Xicom’s X-band SSPAs and BUCs are optimised for challenging low-leakage requirements, as well as being high in power density, highly efficient and compact. They are ideal for fixed, transportable, manpack, and mobile military applications.

Comtech [has] invested heavily to build out a comprehensive X-band product line to support military fixed and transportable terminals with the most challenging performance and environmental requirements,” said Fred Kornberg, Chairman of the Board and CEO. "Our end-customer remains pleased with the outstanding technical performance and reliability of these Comtech BUCs, and we are proud of our track-record on this critical military program.”
