摘要: 本文利用电抗补偿的概念对集成串联体效应振荡器进行电抗补偿,使调谐带宽增加。在C波段,相对调谐带宽达10％以上;输出功率大于30毫瓦;起伏小于3dB。给出了调谐带宽的解析表达式和振荡器电路的设计。 这种宽带集成体效应振荡器采用微带和同轴相结合的结构。变并联谐振为串联谐振,频率调整比较方便,在雷达和通信上得到了广泛的应用。

Abstract: By the use of the concept of reactance compensation, the integrated series bulk effect oscillator, being compensated to increase the tuning bandwidth is reported. In C-band, the relative bandwidth is greater than 10 percent,the output power is greater than 30 mW, and the change of power is less than 3 dB. The analytical expression of tuning bandwidth and the design of oscillator circuit are given.The combined microstrip with coaxial line structure is adopted for the oscillator. Shunt resonance is changed into serier resonance. The integrated wideband bulk effect oscillator has a wide application in radar and radio communication. -
