RESONATOR FILTER AND DIPLEXER WHICH INCLUDES A TRIPLE MODE RESONATOR AND DUAL MODE RESONATOR CAPABLE OF CONTROLLING FREQUENCIES ACCORDING TO A RESONANCE MODE OF THE RESONATOR

摘要

PURPOSE: A resonator filter and a diplexer which includes a triple mode resonator and dual mode resonator are provided to alternatively use the triple mode resonator and dual mode resonator with the similar shape as the triple mode resonator, thereby controlling frequencies of each resonance mode.;CONSTITUTION: A first dual mode resonator(110) comprises independent control parts which control each frequency according to two resonance modes. A triple mode resonator(130) comprises independent control parts which control each frequency according to three resonance modes which are different from the two resonance modes. A first combining part(120) electrically and mutually combines the first dual mode resonator and triple mode resonator. A second dual mode resonator(140) comprises independent controlling parts which control each frequency according to two resonance modes which are different from the three resonance modes and two resonance modes. A second combining part(150) electrically and mutually combines the triple mode resonator and second dual mode resonator.;COPYRIGHT KIPO 2012
