A Six-Way Power Divider For Dual-Band Applications

In this paper, a dual-band power divider is designed to equally split the input power between six output ports. The dual-band feature is implemented using pi-shaped dual-band impedance transformers. Instead of the stubs usually used in such transformers, impedance buffers are used to avoid impractical line widths. A prototype operating at 0.9/1.4 GHz is fabricated, and its simulation and measurements results are presented. The measured output power levels of the prototype at each band are within 0.75 dB from their theoretical values, and good input matching(<-18 dB) is observed at both bands.
