DIELECTRIC FILTER OF INTRA-BAND GROUP DELAY FIXED TYPE AND AMPLIFIER OF DISTORTION COMPENSATING TYPE USING IT

摘要

PROBLEM TO BE SOLVED: To provide a delay filter capable of obtaining many group delay in a desired bandwidth by a small number of stages. SOLUTION: A capacitor is connected in parallel between capacitors to be connected with a dielectric resonator and the other end of it is connected or connected through the capacitor to obtain many group delays of a small number of stages where group delay characteristics never has a large peak in the neighborhood of an edge on the upper side of a pass band and a group delay fixed band is wide.
