A design of the multi-channel microwave frequency conversion micro-module based on full wave electromagnetic simulation

This paper presents the simulation and design of a multi-channel microwave frequency conversion micro-module integrated on a multi-layer ceramic substrate using a full-wave electromagnetic algorithm. The micro-module operates in a frequency range up to 40 GHz and comprises five frequency conversion channels, each isolated within individual metallic shielded cavities. Finite element method is utilized to analyze the insertion loss and return loss of the single channel, isolation between dual channels, as well as the resonant characteristics of the isolation cavity. Additionally, the RF transmission performance of the single channel is tested using a probe station, and the test curves matched well with the simulation results within 40 GHz.
