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.
