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).
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 ?/4 impedance transformers are selected for impedance matching by the PIN diodes. Any output port can be the transmission port through the PIN diodes. For multi-way power divider/combiner, the size of reconfigurable matching network can be reduced greatly. For verification, an eight-way RPD is designed and fabricated. 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. The isolations between transmission ports are higher than 16 dB. The size of the eight-way RPD is 0.23 *0.4 ?(2)(g).
