A new balanced to balanced (BTB) filtering power divider (FPD) based on right triangle substrate integrated waveguide (SIW) cavity is proposed in this article. TE 120 ‐mode is used in four SIW right triangle cavities to realize required differential‐mode (DM) transmission and common‐mode (CM) suppression. Grounded resistors are loaded between DM output ports to obtain port‐to‐port isolation. The transmission zero out of the passband is generated by suppressing the TE 210 mode. A prototype BTB FPD operating at 14.91 GHz is designed, fabricated, and measured for verification. Good accordance between simulation and measurement can be observed.
