A quasi-lumped dual-mode reconfigurable eight-way filtering power divider (FPD) is presented. Two operating modes are one eight-way tunable FPD and one all stopband filter (ASF) with high suppression. The measured eight-way FPD can be tuned from 1.0 to 2.15 GHz, corresponding to the frequency tuning range (FTR) of 73%. The ASF is obtained by misaligning resonant frequencies of LC resonators and weakening their coupling. The proposed dual-mode FPD has the advantage of wide FTR, compact size, high isolation, ultra-wide isolation BW, and high suppression.
