Summary: A design method of N-way reconfigurable power divider (RPD) with N transmission modes and 2(N)-1 states based on reconfigurable impedance matching network (RIMN) is proposed. The RIMN is composed of M parallel ?/4 impedance transformers with different characteristic impedances and PIN diodes and can realize 2(M) -1 different characteristic impedance. The proposed eight-way RPD realizes 8 transmission modes and 255 states. The measured results show that the insertion losses are less than 2.8 dB and the isolations between transmission ports are higher than 16 dB. The size of the eight-way RPD is 0.23 *0.4 ?(2)(g).

Summary: A novel n-way topology is proposed for designing multiway wideband filtering power dividers, which consists of n-coupled multimode resonators and resistors. The wideband filtering response is achieved by employing stub-loaded multimode resonators and shunt resistors between adjacent resonators. The frequency responses of power division and isolation are analyzed based on even-odd mode, and prototypes of three-way and four-way wideband FPDs are designed and fabricated to verify the feasibility of the proposal.

Summary: This paper presents the design of a dual-band six-way power divider with equal and unequal power division capabilities. The unequal design allows for four different output levels at each band and achieves band-distinct power division ratios. The proposed divider incorporates dual-band pi-shaped impedance transformers to realize these capabilities. Analytical derivation of the S-parameters and a detailed design procedure are provided. Four prototypes operating at 0.9/1.4 GHz are fabricated and measured, demonstrating close agreement between measured and theoretical values for output power levels and good input matching (<-15 dB) at both bands.
