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。
Using multi-loop program, developed eight millimeter wave phase-locked source system. Experiments show that the phase noise of 34.7GHz frequency point output (when the Fourier frequency is 1kHz) is -78dBc / Hz, spurious better than-60dBc, the output power is greater than 40mW.
