摘要：

Electronically tunable dielectric resonators and filters operating at frequency about 2 GHz containing axially magnetized ferrite elements have been investigated. Employing axially magnetized ferrites 40 MHz tuning range was obtained with Q-factor greater then 3000. For such structures tuning speed of the order of milliseconds was achieved. The measurements of the trial narrow band filter showed 18 MHz bandwidth at 2.2 GHz without degradation of the RL characteristic and losses lower than 0.8 dB.
