Mixed coupling modified trisection (MCMT) and its applications to substrate integrated waveguide (SIW) filters are presented. By using source or load to replace a resonator and introducing mixed coupling into conventional trisection, the proposed MCMT not only reduce one resonator but also adds a transmission zero (TZ) to improve the stopand. Moreover, the resonators in MCMT can be embedded into multilayer LTCC substrate to achieve a more compact area. Two SIW filters with two TZs are designed and fabricated to validate the proposed method. Measured results which exhibit good selectivity, agree well with simulated ones.
