| 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. |
