Abstract :
A simple technique for rapid tuning of a dielectric resonator using piezoelectric actuation is described. Results are presented for three dielectric resonator materials with relative permittivities of 9.5, 47 and 100 and dielectric Q-factors of 50000 (10 GHz), 9000 (5 GHz) and 16000 (3 GHz). The advantage of the proposed tuning method is that little degradation in the device Q-factor is observed even with tuning up to 2%
