本文阐述了Ｋａ波段频率综合器的研究方案及实现方法，主要包括毫米波主环、微波参考环和中频锁相环的构成，以及用此方法设计实现的输出频率为２６．５～４０ＧＨｚ，频率间隔１ＭＨｚ，相位噪声指标￡（１０ｋＨｚ）＜－６５ｄＢＣ／Ｈｚ，杂散优于－５５ｄＢＣ，输出功率大于＋５ｄＢｍ的毫米波频率综合器。论文同时研究了毫米波频率综合器中所需的微波参考源，其频率范围为２．６１～３．９６ＧＨｚ，相位噪声指标￡（１０ｋＨｚ）＜－（８８～９３）ｄＢＣ／Ｈｚ，输出功率＋１６ｄＢｍ，杂散和谐波抑制优于５５ｄＢ。
This paper describes the Ka band frequency synthesizer research programs and implementation methods, including the millimeter wave main ring, microwave reference ring and intermediate frequency phase-locked loop structure, and the use of this method designed to achieve the output frequency of 26.5 ~ 40GHz, the frequency Interval 1MHz, phase noise index £ (10kHz) <- 65dBC / Hz, spurious better than-55dBC, the output power is greater than +5 dBm millimeter-wave frequency synthesizer. In the meantime, the microwave reference source needed in the millimeter-wave frequency synthesizer is researched. The frequency range is 2.61 ~ 3.96GHz, the phase noise index £ (10kHz) <- (88-93) dBC / Hz, the output power + 16dBm , Spurious and harmonic suppression better than 55dB.
