星载固态功率放大器:迈向极高频
Solid-state power amplifiers for space:going to extremely high frequency
摘要
Abstract
Concentrating on the high frequency demands of solid-state power amplifier(SSPA)for space usage,the methodology and key techniques of the Q band 20 watts,V band 10 watts and W band 2 watts SSPAs are pro-posed in the present study. The GaN HEMT monolithic microwave integrated circuits(MMICs)are utilized as ba-sic power amplifier units for power and efficiency enhancement. The high efficiency multi-ways low loss power combination techniques including magic T and radial-line were developed to achieve high output power. Copper diamond and heat pipes were applied to overcome heat dissipation and thermal flux challenges. By considering the strictly space qualification and components derating requirements,all products show state-of-art performances, which are used and verified in application for satellites payloads or terminal transmitters. To the authors knowl-edge,this is the first time the EHF band SSPA are developed and qualified for space usage in China. The designs proposed in the paper meet the demands and requirements for future satellite projects,to strongly support high fre-quency and high throughput space communication tendency and targets realization.关键词
