MICROMINIATURE RF HIGH FREQUENCY FILTER

摘要

PURPOSE: A micro-scale wireless high-frequency filter is provided to minimize failure rate in a filter tuning process by including a longitudinal opening and a plurality of resonance rods which is protruded through the opening. CONSTITUTION: A board shape housing includes a longitudinal opening and a plurality of resonance rods(110a, 110b) which is protruded through the opening. A plurality of thread holes(150a, 150b) is formed in the position of the housing which corresponds to the end part of the resonance rods. Input-output connectors are formed on both longitudinal direction ends of the housing. The input-output connectors are connected with the resonance rods. A plurality of tuning screws(210a, 210b) is combined with the thread holes. The protrusion degree of the resonance rods is regulated using the tuning screws.
