本文叙述了宽带场效应晶体管固态电调振荡源(FETVCO)的设计。本方法是以测得的[S]参数(大信号)为基础,采用通用的设计原则,并进一步采用CAD设计,以提高设计精度和准确性。文章最后给出了C、X、Ku波段FETVCO的实验结果,取得了近40％的调谐带宽。 This article describes the design of a wideband field effect transistor solid state temperture source (FETVCO). The method is based on the measured [S] parameters (large signal), using common design principles, and further use of CAD design to improve design accuracy and accuracy. Finally, the experimental results of FETVCO in C, X, Ku band are given, and the tuning bandwidth is nearly 40%.
