STUDY OF Ka-BAND PLL SYSTEM
-
摘要: 利用多环方案,研制了八毫米波锁相源系统。实验表明,34.7GHz频率点输出的相位噪声指标(傅氏频率为1kHz时)为-78dBc/Hz,杂散优于-60dBc,输出功率大于40mW。Abstract: An 8mm wave PLL system is designed and manufactured by use of multi-loops. It is measured that the phase noise of mm-wave PLL source is-78dBc/ Hz (Fourier frequency is 1kHz offset carrier 37.4 GHz), spurious is lower than-60 dBc, output power is higher than 40mW.
