In order to solve the problem of poor spurious suppression characteristics of traditional microwave mixers when high-throughout satellite(HTS) transponder is used in broadband applications,which leads to the degradation of transponder performance. This paper presents a microwave photonics(MWP) mixer design that uses integrated photonic filters to suppress optical carriers and unused sideband. The high integration, tunability, high suppression, and low loss characteristics of the integrated photonic filters are fully utilized. By the tuning of the phase parameters of the filter’s micro-rings, the pass of the upper and lower sidebands is realized respectively, thus 30GHz to 20GHz downconversion and 30GHz to 40GHz upconversion have been realized respectively. Analysis and simulation of the MWP mixer has been done, the result shows that the conversion loss of the mixer is -20dB,noise figure is 25dB, which is close to microwave mixer. At the same time, the LO spurious suppresion is improved by 60dB, IIP3 is improved by 12dB. The design achieves a breakthrough in the technical limitations of traditional microwave mixer, and lays a theoretical and technical foundation for the future application of MWP technology in high-throughout satellite.
