【摘要】 简单的毫米波固态源的频率稳定度和相位噪声较差，难以满足要求，采用低频率的高性能频率源倍频实现高性能的毫米波信号源是一种可行的方案，因此有必要研究毫米波倍频器。本文研究了毫米波微带传输线的特性，介绍了变容管的特性及变容管倍频器倍频原理，讨论了变容管倍频器的设计方法，采用微带线作为毫米波电路的传输线，运用ADS(Advanced Design System)2003A软件进行优化得出微带低通滤波器、带通滤波器、各匹配电路及偏置电路和交指隔直电路。最后对微带到波导的过渡形式进行了探讨，采用了双面对极鳍线过渡。采用突变结变容管研制完成的八毫米波微带变容管二倍频器。更多还原

【Abstract】 With the developing of millimeter-wave communication and radar, the demand onmillimeter-wave source is more and more strict. And millimeter-wave solid-stateoscillators can’t meet the demands of some systems. It is necessary to developmillimeter-wave multiplier source. First of all, the character of the micro strip transmissionline is introduced. Then the character of the varactor diode and the principle of frequencymultiplier are studied. And the design method of the frequency multiplier discussed.Microstrip is used as transmission line of varactor frequency multiplier circuitry. Thenrelying on the ADS(Advanced Design System) software, the low pass filter, the band passfilter, embedding impedances matched circuits, bias voltage circuitry and Interdigitalblocking circuit are designed. The double face great fins line transition is used in order totest conveniently. At last, an 8mm frequency multiplier is developed with varactor.更多还原
