Dielectric substance drop-in filter

Abstract

Abstract PURPOSE:To prevent the deterioration of performance due to the connection with other units with small size and ease of adjustment, by dropping in the filter on a part of the MIC (circuit integration for microwave) circuit in module and enabling to use the input and output line on the board through the connection with ribbon. CONSTITUTION:The groove 6a is provided in the MIC module case 6, and the dielectric resonator 1 and the adjusting dielectric substance rod 2 of the resonator 1 are provided in the groove, and further, the dielectric supports 4a, 4b supporting the resonator, adjusting screw 3, and the dielectric substance board 5 for strip line are provided. A plurality of dielectric resonators 1 are arranged and dropped in the shield groove 6a provided with the module case 6 and the input and output side is coupled with the bandpass filter with the input and output lines 5b, 5c provided on the dielectric substance board 5.
