摘要: 本文提出了用負(fù)阻非線性網(wǎng)絡(luò)模型來(lái)表征短槽混合電路功率合成器相互注入鎖定現(xiàn)象的新思想,該模型比較完整地反映了相互注入鎖定中的非線性特性,在導(dǎo)出了功率合成系統(tǒng)的非線性方程之后,給出了達(dá)到最大功率合成效率時(shí)振蕩器工作參數(shù)的優(yōu)化方法。優(yōu)化結(jié)果與實(shí)驗(yàn)結(jié)果吻合較好。

Abstract: A new idea of representing the mutual injection locking phenomena in the short-slot hybrid power combiner by a model of negative nonlinear network is proposed. This model thoroughly represents the nonlinear characteristic of the combiner. After the nonlinear equations of the combining system are derived, a method of optimizing the parameters of the combined oscillators to achieve a maximum power combining efficiency is given. The optimum results agree with experimental ones quite well. -
