Ka频段鳍线电调振荡器

Ka BAND FINLINE ELECTRONICALLY TUNED OSCILLATOR

介绍了一种由鳍线、耿氏器件和梁式引线变容管构成的混合集成电调振荡器电路及其设计方法．给出的ＶＣＯ电路结构简单，利用其等效电路模型，可方便地对振荡器在所需工作频率上的电调带宽进行优化设计．经优化设计的电调振荡器性能的测试结果为：在３４．９３ＧＨｚ的频率处，具有１．２ＧＨｚ的电调带宽，带内功率输出为２０．６５±０．５２ｄＢｍ．

A Ka band hybrid integrated electronically tuned oscillator by using finline, Gunn device and beam lead varactor diode was presented. And its designing method was also introduced. The VCO equivalent circuit model presented can be conveniently optimized to get wide electronically tuned bandwidth and simple structure. The measured performances of the optimized VCO are 1.2GHz (electronically tuned bandwidth) and 20.65±0.52 dBm (output power) at 34.93GHz (frequency).
