| This thesis presents the design and manufacture of a V-band frequency quadrupler. This V-band frequency quadrupler consists of the Ka-band MMIC frequency doubler, the Ka-band band-pass filter, the V-band varactor frequency doubler, and the microstrip-to-waveguide transition. The principles, design method and design process of varactor frequency doubler are presented particularly.Ansoft Serenade and Ansoft HFSS were used to design, optimize and simulate the circuits. A V-band frequency quadrupler was made and tested, the power of input signal is 15dBm, the power of output signal is greater than 9.8dBm 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. |
