LSSC Solid-State High-Power Amplifiers

For several decades high-power tracking and imaging radars around the world have been reliant on vacuum electron devices (VEDs) to power them. Increased cost, dwindling know-how, long delivery time, and limited commercial providers has led radar engineers to consider solid-state alternatives. This paper reports on several efforts to develop alternative solid-state RF high power amplifiers that span a broad RF spectrum (VHF to W-band) and could potentially serve as an alternative to aging VED technology.
