摘　　要：目前毫米波倍频器在毫米波频率合成器中已经得到了广泛的应用,利用毫米波倍频器可以获得具有宽带特性的毫米波频综及多点的频率输出。文中主要介绍一种基于高性能数字集成芯片PE3236设计的X波段四倍频器。通过将高稳定度频率合成器输出的S波段信号四倍频,并滤除杂散和谐波以达到倍频的效果。文中所设计的毫米波四倍频器输出功率为-11.356 dBm,相位噪声为-78.4 dBc/Hz@1 kHz,对杂散的抑制优于-45dBc。The frequency multiplier at millimeterwave band is used widely in millimeterwave frequency synthesizers. A Xband fourth frequencymultiplier based on high performance digital monochip PE3236 was presented. The signal was obtained by multiplying the signal to fourth, gained from a high stabilization frequency synthesizer with the spurious and subharmonic wave removed and suppressed. The designed microwave multiplier＇ s output voltage is -11. 356 dBm, its phase noise is -78.4 dBc/Hz@ 1 kHz, and the suppression to spurious is better than -45 dBc.
