Abstract

A novel ultra-wide band CPW(Coplanar Waveguide) balun having the structure of multistage Wilkinson power divider is proposed. It has an 180° phase inverting structure between signal line and ground planes of CPW transmission line. The 3-stage Wilkinson power divider is transformed directly into the ultra-wide band balun without any cost of the size and performances. The measurement shows the right S-parameters as a power divider and the proper out of phase as a balun. The measured amplitude and phase unbalances at output ports are ± 0.5dB and ± 6°, respectively over 800∼3200MHz, while the maximum insertion loss is 0.8dB.
