journal contribution
posted on 2024-11-23, 06:53 authored by Ernest Fardin, Anthony HollandAnthony Holland, Kamran GhorbaniKamran GhorbaniA method for tuning the centre frequency of a 3 dB hybrid coupler using varactor diodes is presented. The circuit is suitable for recon-figurable 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.
