Abstract
Varactor tuned microstrip ring resonators have been developed with more than 30 percent tuning bandwidth using packaged hyperabrupt junction varactor diodes. The experimental tuning bandwidth was found to be in very close agreement with the predicted value obtained using analysis based on transmission line modelling. The attractiveness of the approach presented lies in its simplicity, the tuned resonator could find applications in microwave oscillator circuits and frequency agile communication systems.<>
