TUNABLE FILTER ENABLING ADJUSTMENT OF TUNING CHARACTERISTIC AND TUNING RANGE

摘要

PURPOSE: A tunable filter is provided to be adaptively used in various environments by enabling a user to control a tuning property and a tuning range. CONSTITUTION: A resonator(310) is received at a cavity(308). A sliding member(312a,312b) is installed on the upper side of the resonator. A control bolt is combined with the sliding member through a bolt hole. A thread is formed on the side of the control bolt. A tuning element(330) is combined with the lower side of the control bolt and is located on the upper side of the resonator. The bolt hole has a thread. A distance between the tuning element and the resonator is controlled by the rotation of the control bolt.
