Magnetically tunable dielectric resonators operating at frequencies of about 2 GHz
Abstract
Electronically tunable dielectric resonators operating at frequencies of about 2 GHz containing axially and circumferentially magnetized ferrite elements have been investigated. Employing axially magnetized ferrites, a 40 MHz tuning range was obtained with Q-factor greater than 3000. For such structures the tuning speed of the order of milliseconds was achieved using helical enclosure of the dielectric resonator instead of a metal cavity. Resonators containing circumferentially magnetized ferrites were constructed whose resonant frequencies can be switched by short current pulses between two stable values that differ in frequency up to 15 MHz.
