本文介绍一种四管功率合成体效应振荡器。这种功率合成器结构简单、体积小、重量轻,适合于空间电子设备使用。振荡器最大功率输出为1.2—1.5W,功率合成率近100%,直流—微波转换效率达3.8%。功率合成器采用了双金属结构和介质加载的“综合”补偿法,相对频温系数达到2×10~(-5)/℃。工作在注入锁定状态,增益为16db时锁定带宽为40MHz。
This article describes a four-tube power combiner effect oscillator. This power synthesizer has the advantages of simple structure, small size and light weight, and is suitable for use in space electronic equipment. Oscillator maximum power output of 1.2-1.5W, power synthesis rate of nearly 100%, DC - microwave conversion efficiency of 3.8%. The power synthesizer uses a “comprehensive” compensation method with a bimetallic structure and dielectric loading, with a relative frequency coefficient of 2 × 10 -5 / ° C. Work in the injection lock state, the lock bandwidth is 40MHz when the gain is 16db.
