【摘要】 本文对V波段有源倍频器进行了设计研究。该倍频器的设计在国内首次采用直接四次倍频放大的方案来实现,整个倍频器主要由V波段PHEMT四倍频器、V波段微带耦合带通滤波器、V波段输出放大器以及V波段探针型微带—波导转换器等几部分电路组成。其中重点论述了有源倍频器的工作原理、设计方法以及详细的设计过程。 在整个设计过程中,充分利用了射频微波电路仿真设计软件Agilent ADS和Ansoft Serenade以及电磁场仿真设计软件Ansoft Ensemble和HFSS对电路进行设计和优化。根据仿真优化结果得到了V波段有源倍频器,当输入功率为6dBm时,在整个55.6~56.4GHz的工作频带内输出功率大于9dBm。该V波段有源倍频器可用于将微波信号拓展到毫米波段,为毫米波系统提供高稳定的本振源。

【Abstract】 The thesis presents the research and design of a V-band frequency quadrupler. A direct EET quadrupler project was adopted first internally. The V-band frequency quadrupler mainly consists of the V-band PHEMT doubler, the V-band coupling microstrip band-pass filter, the V-band output amplifier, and the microstrip to waveguide transition.The principles, design method and process of PHEMT frequency doubler are presented particularly.Microwave and RF circuit simulation tools such as Agilent ADS, Ansoft Serenade and electromagnetic simulation tools such as Ansoft Ensemble and HFSS were used to design, simulate and optimize the circuits. The V-band frequency quadrupler was simulated, the power of input signal is 6dBm, and the power of output signal is greater than 9dBm over the 55.6~56.4GHz frequency range. This V-band frequency quadrupler can provide an ultra stability millimeter-wave source for the system of the millimeter-wave intersatellite link by quadrupling the frequency of a microwave source.
