Abstract:

The design of passive components in quadruple Sub-harmonic image rejection mixer is presented in this study. The passive components include double-balun and Lange coupler. With the help of ADS, a Balun with magnitude imbalance degree less than 0.2 dB and phase imbalance degree less than 1 is achieved in the range of 7.9 9.5 GHz. The insertion loss is about 7.3 dB at the center frequency of 8.7 GHz. A Lange coupler with magnitude imbalance degree in the range less than 0.3 dB and phase imbalance degree less than 1 is realized over the 30~40 GHz measurement band. The insertion loss is about 3.25 dB at the center frequency of 35 GHz. Satisfactory results have been reached in the simulation of double-balun and Lange coupler, which makes a significant foundation to the realization of the monolithic quadruple Sub-harmonic image rejection mixer.
