Multi-Band Synthesizer, Power Amplifier, and Filter Development

摘要

This final report describes three research and development projects conducted by Synergy Microwave Corporation for DARPA (Defense Advanced Research Agency). The purpose of these projects was to develop and demonstrate the key sub-systems needed for an u1tra-high performance, low cost, multi-band tactical transceivers. These devices include: 1) A 25 MHz to 2,500 MHz, 5 W power amplifier, 2) A 2.5 GHz to 6 GHz synthesizer to be used the receiver's first local oscillator, and 3) A 25 MHz to 3,000 MHz tunable filter that can be used as a preselector or a post power amplifier filter. The report has five chapters. The first chapter is an introduction. The second chapter describes the amplifier. The third chapter describes the synthesizer. The fourth chapter describes the filter. The fifth chapter provides a summary.
