A Tri-Band Gysel Power Divider Based on Tri-Band Phase Inverter

摘要

A novel tri-band Gysel power divider is proposed. The tri-band GPD is realized by replacing the wideband PI of wideband GPD with the tri-band PI. Its structure is simple and the 3 working bands are more flexible (0<$f$1/$f$3<1/2, 1/2 2/f3 <1, $f$123) than the previous job. A tri-band GPD with working bands of Digitally Enhanced Cordless Telecommunications System (DECT, f1: 902MHz~928MHz, f2: 1880MHz~1990MHz, f3: 2400MHz~2483.5MHz) is simulated and measured. The measured results validate the proposed method.
