Equal and unequal dual-band six-way power divider with band-distinct power division ratios

Abstract

In this paper, a dual-band six-way power divider is designed with equal and unequal power division capabilities. The unequal design of the divider is capable of providing up to four different output levels at each band. Furthermore, it is capable of achieving band-distinct power division ratios. These capabilities are realized in the proposed divider by using dual-band pi-shaped impedance transformers. The S-parameters of the proposed divider are derived analytically, and its design procedure is explained in detail. Four prototypes operating at 0.9/1.4 GHz are designed and fabricated to demonstrate the divider’s capabilities. Simulation and measurements results of the four prototypes are presented. The measured output power levels of the four prototypes at each band are within 1 dB from their theoretical values. Also, good input matching (<-15 dB) is observed for the four prototypes at both bands.
