Development of Rugged, Water Cooled Solid-State RF Amplifiers for Accelerator Applications

Abstract

Recent advances in transistor technology are making solid-state RF amplifiers an increasingly viable alternative to tube systems in accelerator applications. This paper details the development and performance of a range of new high power amplifiers, based on current MOSFET technology, and designed specifically for this application. A generic modular architecture that can be used to construct high power CW amplifier systems operating from HF up to S-band, is detailed. Key design considerations in terms of modularity, redundancy, reliability and cost are discussed.
