In this paper, we present a new frequency-tunable filtering power divider structure and its design method. For achieving the frequency filtering characteristic, the power divider uses a single resonator or multiple resonators. One of the unique features of the presented structure is that the last resonator is coupled to the two outputs, and this allows for minimizing the number of the resonators used in the power divider design. For verifying the presented structure and design method, we have designed filtering power dividers using frequency-tunable substrate-integrated resonators. It is shown that the operating frequency of the divider can be adjusted maintaining excellent impedance matching performance.
