Abstract
In this paper, we propose a method to implement an unequal power divider with different complex termination impedances for different output power ratios. The proposed method was designed using a matching the terminated complex impedances of the output port using only the transmission line, and presented an isolation circuits to satisfy the isolation characteristic between the terminating complex impedance ports. To prove the feasibility of this method, an unequal power divider with different load complex impedances with a splitting ratio k2 = 3 dB and 1.7 dB and an unequal power divider with different complex termination impedances of all ports with a splitting ratio k2 = 3 dB was designed at a center frequency of 2 GHz, and it was confirmed that the measured results of the electrical characteristics agree well the simulation.
