Abstract: In this paper, a general new synthesis design technique of multi-band coupled resonator filtering power dividers (FPDs) is presented, which is promising in both industrial and academic field. After a set of complete closed-form analytical equations are established for direct synthesis design, the proposed method is intensively described to reveal its powerful capacity in design of a multi-band FPD with any pre-specified frequency response of multiple filtering passbands (e. g. any order, number of bands, etc. ), high multi-band isolations and matching. Therefore, this synthesized method can provide a unified design guideline for a multi-band FPD with various specifications as required by modern industrial wireless communications systems. As examples, two third-order dual-band and triple-band microstrip FPD prototypes are designed, fabricated and measured for demonstration. Measured results coincide well with simulated ones, thereby verifying the feasibility of proposed synthesis design method and attractive performances of the designed multi-band FPDs.
