摘要

In this brief, a self-packaged substrate integrated suspended line filtering power divider with wideband and high frequency selectivity by using coupled-line termination added multi-mode resonator has been developed, and has been demonstrated by experiment. Three transmission zeros have been realized due to the coupled-line termination loaded stepped impedance resonator and multi-mode resonator, which improve the frequency selectivity and out-of-band suppression importantly. The wideband filtering power divider has a measured center frequency of 3.9GHz, a fractional bandwidth of 63.6%, an insertion loss of 0.74dB, an in-band isolation (S-23) of no less than 18.3dB, and an out-of-band rejection of more than 40dB.
