Abstract

Recent developments in high temperature superconducting (HTSC) thin films have made possible the construction of microwave resonators with a very high Q values because of the significantly lower surface resistance than that of normal metals. In this paper microwave characteristics of microstrip resonators fabricated from YBa/sub 2/Cu/sub 3/O/sub 7-/spl delta// and Tl/sub 2/Ba/sub 2/CaCu/sub 2/O/sub 8/ thin films were studied and their application for stabilization of a microwave oscillator was shown. Two oscillators were fabricated and tested, one at 4 GHz with YBa/sub 2/Cu/sub 3/O/sub 7-/spl delta// meander-type resonator and a hybrid oscillator implemented on RT/Duroid substrate and Tl/sub 2/Ba/sub 2/CaCu/sub 2/O/sub 8/ linear microstrip resonator operated at 12 GHz. The designs were parallel feedback mode oscillators and transmission-type high-Q HTSC resonators were used as bandpass filters. A frequency instability of the hybrid oscillator with Tl/sub 2/Ba/sub 2/CaCu/sub 2/O/sub 8/ resonator of -0.16 ppm/K at 77 K was achieved which exceeds that possible with state-of-the-art DROs and SAWOs at 12 GHz.

基于HTSC谐振腔的高热稳定性微波振荡器

高温超导(HTSC)薄膜由于其表面电阻明显低于普通金属，使得构造具有非常高Q值的微波谐振器成为可能。本文研究了由YBa/sub 2/Cu/sub 3/O/sub 7-/spl δ //和Tl/sub 2/Ba/sub 2/CaCu/sub 2/O/sub 8/薄膜制成的微带谐振器的微波特性，并展示了它们在稳定微波振荡器中的应用。制作并测试了两个振荡器，一个是在4 GHz工作的YBa/sub 2/Cu/sub 3/O/sub 7-/spl delta//曲流型谐振器，另一个是在RT/Duroid衬底上实现的混合振荡器，工作在12 GHz的Tl/sub 2/Ba/sub 2/CaCu/sub 2/O/sub 8/线性微带谐振器。设计了并联反馈模式振荡器和传输型高q HTSC谐振器作为带通滤波器。采用Tl/sub 2/Ba/sub 2/CaCu/sub 2/O/sub 8/谐振腔的混合振荡器在77 K时达到了-0.16 ppm/K的频率不稳定性，超过了目前最先进的ro和sawo在12 GHz时的频率不稳定性。
