摘要

利用新研制的介电谐振腔，研制了具有极高频率稳定性的GaAs场效应管MIC振荡器。设计介质谐振腔的关键是使谐振频率与温度呈线性关系。该特性是在锆酸盐陶瓷的叠层式介质谐振器中实现的。在-20至+60/spl度/C的温度下获得的/spl plusmn/85 kHz的频率稳定性足以用于调幅高频电视接收机。

A Frequency-Stabilized MIC Oscillator Using a Newly-Developed Dielectric Resonator

A GaAs FET MIC oscillator with very high frequency stability has been developed using a newly-developed dielectric resonator. The key to designing the dielectric resonator was to make the temperature dependence of the resonance frequency linear. This characteristic was realized in a stacking-type dielectric resonator with zirconate ceramics. The obtained frequency stability of /spl plusmn/85 kHz in temperatures -20 to +60/spl deg/C is sufficient for AM SHF TV receivers.
