引言采用封装的器件与分布电路的变容管调谐耿效应振荡器在已往的文献中已有报导。这种振荡器的调谐带宽最终受到两种因素的限制:1)不希望的二极管之壳散杂电抗;2)分布电路表现出的频率依赖关系,以致不能在宽带内工作。针对这些情况,试图制作一种使用未封装的器件,用集总元件薄膜电路的宽带振荡器。振荡器描述 Introduction Varactor tunings using packaged devices and distributed circuits Geng effect oscillators have been reported in previous literature. The tuning bandwidth of such an oscillator is ultimately limited by two factors: 1) the unwanted diode cascode reactance; and 2) the frequency distribution of the circuit shown to be frequency dependent so that it can not operate in wideband. In response to these circumstances, an attempt was made to use a broadband oscillator using a lumped element film circuit using an unenclosed device. Oscillator Description
