中文摘要:聚焦于星载固态功率放大器的高频化,文章设计并实现了Q频段20W、V频段10W以及W频段2W的固态功率放大器。基于氮化镓功率单片技术,提升了单元的功率和效率;基于魔T和径向线的高效率、低插损多路功率合成技术,实现了整机高功率输出;铜金刚石和热管的应用和工艺攻关,克服了多热源、高热流的工程瓶颈。Q频段和W频段固放首次在轨应用,以及V频段固放在地面发射机中的应用。考虑到严苛的空间考核条件以及器件为满足在轨长寿命的降额要求,产品均性能优良稳定。文中的Q频段和W频段固放是我国首次开发并在轨搭载验证的星载连续波固态功率放大器,为我国后续极高频段高通量卫星的载荷实现提供了有力技术支撑。

Solid-state power amplifiers for space: going to extremely high frequency
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 were proposed in the present study. The GaN HEMT monolithic microwave integrated circuits (MMICs) are utilized as basic 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 knowledge, 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 frequency and high throughput space communication tendency and targets realization.
