一、引言体效应振荡器作为毫米波信号源获得广泛应用。目前许多研究工作仍致力于发展宽带调谐的毫米波体效应振荡源以及毫米波功率合成器。特别是我国在耿氏器件的研制方面有了长足的进步,为发展毫米波固态源提供了有利条件。对于GaAs体效应振荡器,当频率高于～
I. Introduction The body-effect oscillator is widely used as a millimeter-wave signal source. At present, many research work is still devoted to the development of broadband tuned millimeter wave oscillator and millimeter wave power synthesizer. In particular, China has made great strides in the development of Gunn devices, which has provided favorable conditions for the development of millimeter-wave solid state sources. For GaAs body effect oscillators, when the frequency is higher than ~
