A substrate integrated waveguide (SIW) resonators coupled cascaded filtering power divider (FPD) is proposed in this paper. The fusion topology of filter and power divider is realized by setting three-cavity coupling structure. The orthogonal feed cavity is used as the output cavities, and the transmission zero (TZ) is generated into the frequency response. A design example is obtained by simulation. The simulation results show that the center frequency is 35.34 GHz, the relative bandwidth is 3.31%, and a TZ with strong suppression is generated in upper stopband at 36.5 GHz.
