摘要 描述了工作频率达1.435GHz的低损耗声表面横波谐振器,其损耗为3dB,有载品质因素达1 573。用此表面横波谐振器作为频控元件,采用Colpitts型振荡电路,制作出千兆赫兹频率的低噪声声表面横波振荡器,其在偏离载波1kHz、10kHz、1MHz处的相位噪声分别达-105dBc/Hz、-137dBc/Hz、-168dBc/Hz。 This paper introduces a low loss surface transverse wave resonator of 1. 435 GHz frequency, Its inser- tion loss is 3 dB,and loaded Q is 1 573. Using it in Colpitts type oscillating circuit,it has a low phase noise that is --105 dBc/Hz,--137 dBc/Hz,- 168 dBc/Hz at 1 kHz, 10 kHz, 1 MHz of the carrier of the surface transverse wave oscillator.
