Design of a K-band frequency conversion module

Abstract： In this article, a K-band frequency conversion module is designed, which includes up and down conversion channels to achieve frequency conversion between K-band RF signals and intermediate frequency signals. By conducting full-link cascading simulation analysis and calculation, the frequency planning of the link was optimized, and the in-band spurious interference was reasonably avoided. Through three-dimensional electromagnetic field simulation, the transmission interconnection structure of the link was optimized, and the inter-stage matching characteristics were improved. The test results show that the component has the characteristics of high spurious suppression system and small in-band gain fluctuation. The spurious suppression is better than 60 dBc, in-band fluctuation is better than±1 dB, and mirror frequency suppression is better than 50 dBc. All other indicators meet the design requirements. This design method also provides beneficial exploration for the design of frequency conversion modules.
