Abstract
A method for tuning the centre frequency of a 3 dB hybrid coupler using varactor diodes is presented. The circuit is suitable for reconfigurable or multifunction transceivers that switch between several narrow frequency bands. A prototype covering the PCS, DCS and IMT2000 cellular bands (1710-2170 MHz) is demonstrated.
