Abstract:
This paper describes the principle, design, simulation and experiment results of a harmonic mixer used for Ku-band microwave receiver. The mixer consists of a Lange coupler, an input filter, an output filter and matching networks etc. From the experiment results, it can be seen that the experiment curve of the conversion loss accords with the simulation curve basically in the 14. 00-14. 25GHz frequency region, the in-band flatness is less than 1 dB and the VSWR less than 2.
