摘　　要：通过比较几种频率合成器的制作方法,提出了采用直接频率合成与锁相器频率合成相结合的方法研制出的X波段频率合成器,它具有杂散抑制高达-75dB、输出频带宽至600MHz的特点。相位噪声为-95dBc/Hz@1kHz,且具有电功耗更低,体积更小,质量更轻等优点。A new design combining direct frequency synthesize and phase locked synthesize is proposed by comparing several frequency synthesize methods. The X-band Frequency Synthesizer has the features of high suppression ( - 75 dB); broad output frequency bandwidth (600 MHz) and low phase noise ( - 95 dBc/Hz@lkHz). It also has the advantages of lower power consumption, smaller size and lighter weight.
