Northrop Grumman High-Power Solid-State Amplifier Will Boost Signal Strength on Intersatellite Links of DoD’s Advanced EHF Communications System

Northrop Grumman engineer displays an innovative, high-performance solid-state power amplifier developed for use in the communications payloads of Advanced EHF satellites. In tests, this prototype amplifier delivered power output of more than 11 watts, exceeding design requirements by more than one-third. At the same time, the unit provides the inherent high reliability of solid-state technology, at about one-tenth the weight of equivalent conventional traveling wave tube amplifiers generally used on satellites. The Department of Defense’s Advanced EHF satellite system will provide high-data-rate, secure communications to U.S. and certain allied forces. The new solid state amplifiers boost the strength of transmit signals that will be sent from satellite to satellite in the Advanced EHF system.
