Abstract :
An X-band 2-pole filter based on uniplanar dielectric resonators (PDR) with ferroelectric tuning was designed and fabricated. PDRpsilas were chosen because of their high Q-factor and the rarefied spectrum of resonance mode frequencies. At frequency ~10.5GHz the filter displayed insertion losses not more than S21=-3dB in the bandwidth Deltaf=110 MHz. The frequency of tuning was DeltaF=420 MHz.
