TUNABLE FILTER COMPRISING CONDUCTIVE PLATES CAPABLE ROTATING

摘要

PURPOSE: A tunable filter for including a rotatable conductive plate is provided to shorten time for tuning a filter by varying a frequency by using a conductive plate rotated by a rotary shaft. CONSTITUTION: A plurality of cavities is formed in a housing(100). A connector is respectively inserted from the outside of a housing to the inside. A resonator(200) is vertically arranged between in input side and output end connectors(120,140). A rotary shaft(260) is rotated while being arranged to cross the housing on an upper part of the resonator. A conductive plate(240) controls a frequency and a bandwidth by varying a distance from the resonator by eccentrically rotating around the rotary shaft while being separated from each resonator at a certain interval.
