摘　　要：基于毫米波锁相源相位噪声理论,明确指出采用低相位噪声的微波频率源可以有效改善毫米波锁相源相噪指标。利用低相位噪声的微波倍频源,结合谐波混频方式,设计出95GHz低相位噪声锁相频率源。测试结果表明,其相位噪声可以低至-90.44dBc/Hz@10kHz,验证了该设计方案的可行性。Based on the phase noise theory of millimeter wave PLL frequency synthesizer, it is indicated that the phase noise of millimeter wave PLL frequency synthesizer can be improved by adopting low phase noise microwave frequency source. A low phase noise microwave multipler source is designed. Combined with harmonic mixing, the 95 GHz low phase noise PLL frequency synthesizer is presented. A phase noise of -90dBc/Hz at 10 kHz offset is achieved, which indicates feasibility of the new scheme.
