X频段10 kW速调管功放在深空地面站的应用

速调管因具有输出功率大、效率高、成本低、工作稳定可靠的优点,在微波发射系统中占据着重要的地位。近年来,国内速调管功放取得了较大的进展,连续波输出功率从几百瓦提升到十千瓦。采用固态+速调管放大方案,设计一套X频段10 kW连续波速调管功率放大器,工作带宽为95 MHz。该功放应用于深空地面站,是深空探测发射分系统的重要组成部分。文中主要描述了速调管功放的组成、主要技术性能和测试结果。测试数据表明,X频段10 kW速调管功放工作稳定、可靠,且完全符合设计要求

Application of X-band 10 kW Klystron Power Amplifier in Deep Space Ground Station

Owing to its high output power,high efficiency,low cost,and stable and reliable performance,the klystron plays an important part in the microwave transmission system.In recent years,the domestic klystron amplifier has made great progress with continuous wave output power increasing from hundreds of watts to ten kilowatts.Using solid state+klystron amplification scheme,a set of X band 10 kW CW klystron power amplifier is designed with an operating bandwidth of 95 MHz.The power amplifier is applied on the Deep Space Ground Station (DSGS),an important part of transmitting system in Deep Space Exploration.This paper describes the X band 10 kW CW klystron amplifier composition,the technical performances and the test results.The test data shows that the X-band 10 kW klystron amplifier is stable and reliable,fully meeting the design requirements.
