| Abstract: | A new dual-band 3 dB three-port power divider with arbitrary impedance terminations is proposed. The structure is composed of a two-section transmission-line transformer and an isolation resistor. Each transmission line's electrical length is /spl pi//3 at the fundamental frequency. Based on an ideal transmission line model, new design equations and graphs are given. The technique is validated by the experimental results on a 3 dB 900/1800 MHz power divider with Z/sub S/=100 /spl Omega/ and Z/sub L/=50 /spl Omega/. Good performances of the proposed power combiner/divider at both frequencies are obtained. |
