Raytheon's SSHPA is a modular, solid-state UHF power amplifier patented adaptive architecture that provides unsurpassed ruggedness and efficiency for airborne, ground, and shipboard communication systems.

As part of the current Airborne Warning and Control System (AWACS) upgrade program, Raytheon is providing the next-generation product for airborne high-power UHF amplification. It provides AM and FM modes for robust voice and data communications. Its internal control loop maintains precise power leveling, plus active modulation correction for exceptionally low added distortion in AM mode. The SSHPA's adaptable control and status interface supports MIL-STD-1553B, EIA-232 optional, and DDM controllers for both airborne and ground applications.
