N2 - A circuit-electromagnetic (EM) co-design approach to predict the power handling of tunable, high-Q, substrate-integrated waveguide (SIW) bandpass filters is presented. The prediction approach is directly applied to a heavily-loaded evanescent-mode cavity filter in bandpass domain. To demonstrate the validity of the design method for structures with severe aspect ratios, a 4% second-order Butterworth, evanescent-mode cavity SIW bandpass filter, with a continuous tuning range from 3.0 to 3.6 GHz is designed, fabricated, and tested. The filter handles 26.9 Wof continuous-wave power at 3.0 GHz as predicted.
