The Novel 3-Way Power Dividers/Combiners Structure and Design

A fabricated 1:3 power divider that provides equal power split to all four output ports over a large bandwidth is presented, which can be extended to an arbitrary number of output ports. A new wideband three-way microstrip power divider implemented on a single-layer printed circuit board (PCB) is presented in this design. The proposed three-way planar power divider consists of a branch lines and a combine line for three output ports of characteristics of equal magnitude and in-phase. To demonstrate the design methodology, one prototype is realized. The new design was simulated and validated by the measurement. Measured results show that 10 dB return loss of the three output ports has been achieved across the bandwidth from 1.8 GHz to 10.5 GHz.
