Abstract In this paper, a small‐size semi‐lumped three‐port power divider with both power and frequency tune is designed and measured. The proposed topology uses complex impedance transformers in each output branch. A 3D CPW prototype is realized with varactor diodes. It exhibits a wide tunable power, from −1.3 to −17 dB, and a wide working frequency tune, from 0.8 to 1.4 GHz. © 2006 Wiley Periodicals, Inc.
