Power Amplifiers Boost HTS Systems

May 26, 2021
Comtech Xicom Technology recently received a $2 million order from a leading HTS system integrator for HPAs capable of 500 W output power at Ka-band frequencies.

High-power amplifiers (HPAs) are essential components for achieving dependable wireless connections in high-throughput-satellite (HTS) communications systems. Based on its durable, high-performance HPAs, Comtech Xicom Technology, a subsidiary of Comtech Telecommunications Corp., recently earned a $2 million contract from a leading HTS systems integrator for gateway HPAs. The amplifiers can generate 500 W ofoutput power at Ka-band frequencies for satellite-communications (satcom) gateway earth stations.

The robust Ka-band amplifiers (see the figure) provide the signal gain and output-power levels to effectively distribute high data-rate signals to and from orbiting satellites in HTS applications for consumer, industrial, and government customers. Such applications typically provide Internet access in areas that may be difficult to reach or are underserved by terrestrial wireless and cable interconnections. Fred Kornberg, chairman of the board and chief executive officer (CEO) of Comtech Telecommunications Corp., noted: “Reliable and affordable broadband internet service is essential in today’s world. People who live and work in rural areas have the same needs as urban users for a high-quality online experience. HTS networks are an ideal way for rural customers to stay connected.” Concerning the HPAs, Kornberg added: “Comtech’s 500-W amplifiers are at the heart of HTS gateway earth stations. We have been supplying the HTS community with 500-W Ka-Band amplifiers since 2009, and they feature high linear power, superior phase noise, and offer great reliability.”

The company offers newer solid-state amplifiers (SSAs) as well as traditional traveling-wave-tube amplifiers (TWTAs) for ground-based and airborne applications covering a total frequency range of 2 to 52 GHz. The Ka-band frequency range includes segments of the range from 26.5 to 40.0 GHz. HTS networks make Internet  connectivity available on the ground, at sea, and on-board in-flight aircraft with wide bandwidths and fast access times
