This Letter presents a miniaturised wide tuning‐range four‐way filtering power divider (FPD). It is mainly developed by integrating a co‐shared varactor‐loaded quasi‐lumped‐element dual‐mode resonator and an isolation resistor, achieving a wide tuning power division ratio (PDR) and centre frequency (CF) simultaneously. The presented tunable four‐way FPD stands out from those in the literature, by both its improved performance (wider tuning range for PDR and CF with nice isolation and matching) and ultra‐compact design layout. To validate the design concept, a reconfigurable prototype is designed, fabricated, and tested. Measured results will coincide with the simulated ones.
