High Power Solid State Amplifiers

The United States Navy currently uses klystron-based and high power modulator tube Radar Transmitters that are increasingly more expensive to own and operate. Daico proposes to ultimately replace specific tube-based Transmitters with fully Solid-State Transmitters (SSTx). The proposed feasibility study will demonstrate significantly higher standards for Availability (Ai), Reliability and Maintainability while reducing Total Cost of Ownership by adapting, to a shipboard environment, our proven, scalable transmitter architecture, called (m+n) Automatic Redundancy Technology Transmitter, (m+n) in short, for coherent transmitters. The (m+n) main building block is an innovative High Power Amplifier design that supports true hot-swapping, automatic failover and graceful power degradation. The first (m+n), invented in 2008 and deployed in a mission critical ASR-3 application in 2010, delivers>99.99% Ai. (m + n) has been commissioned for more than two years without any operating failures to date. The proposed feasibility study will confirm (m+n) is adaptable to shipboard environments, utilizing state of the art solid state technology, with capability>500kW peak output power in frequencies through C-Band. This proposal will demonstrate the feasibility of our innovative High Power Amplifier in various existing Radar Systems, like SPS-49, SPN-43, SPY-1B (Pre-driver), AeroStat and so forth.
