高稳定特高频(UHF)锁相振荡源研究

The Study of Ultra-high Frequency High Stabling Phase-locked Oscillator

本文论述的2700MHz高稳定度锁相振荡源的设计过程。用10MHz晶振对2700MHz压控振荡器进行锁相，改善了输出信号指标。相位噪声指标为：L（10kHz）＜－93dBC／Hz输出功率大于10mW．杂散仰制＜－65dBC。

The paper discusses about the process of designing 2 700 MHz high stability phase-locked oscillator. Using of 10 MHz crystal oscillation to phase lock 2 700 MHz piezoelectric oscillation,the design sets a better norm of output information: norm of phase noise is L (10 kHz ) < - 93 dBC/Hz,output power> 10 mW,stray restraint< - 65 dBC.
