A Varactor Diode based Power Divider with Frequency-Bandwidth Tuning

A reconfigurable power divider with a com-pact structure is presented in this work. A varactor cas-caded by a transmission line at the input port and a shunt-connected varactor placed across the output ports acts as reconfigurable units. The divider provides good isolation and matching in the entire reconfigured operating band. To justify the adopted design topology a reconfigurable power divider with 2.4 GHz center frequency is designed and simulated. The obtained results indicates that the power divider has a wide tuning range along with better return loss and isolation in the entire tuning range,
