Abstract
This paper describes micromachined bandpass filters design at K band on GaAs and silicon substrate, respectively. The performance of three-layer (supported by 2 um AlGaAs membrane) and two-layer (solid) filter structure on GaAs substrate are compared and discussed. Electromagnetic simulation shows less than 1dB insertion loss and acceptable stop band rejection for both the solid two-layer and membrane three-layer filter structure. A two-layer filter structure with cavity on bottom wafer is also proposed on silicon substrate, where a 10 um SiO2 is used as a membrane. Both EM simulation results and mechanical analysis are provided. The boundary element method is used in mechanical simulation and the deflection of about 1.338 um is obtained for SiO2 membrane.
