DIELECTRIC MONO-BLOCK TRIPLE-MODE MICROWAVE DELAY FILTER FOR PROVIDING FLAT GROUP DELAY OVER WIDE FREQUENCY RANGE

摘要

PURPOSE: A dielectric mono-block triple-mode microwave delay filter is provided to reduce effectively undesired signals by coupling a triple-mode resonator to an assembly of a mask filter and a low pass filter. CONSTITUTION: A resonator having a flat group delay filter includes a first triple-mode mono-block, a second triple-mode mono-block, a first probe, and a second probe. The first triple-mode mono-block(10) and the second triple-mode mono-block(12) are coupled through an aperture. The first probe(20) is located at an end of the first triple-mode mono-block. The second probe(22) is located at an end of the second triple-mode mono-block opposite to the end of the first triple-mode mono-block.
