Title:
MULTI-POLAR CASCADE QUADRUPLET BAND PASS FILTER BASED ON DIELECTRIC DUAL MODE RESONATORS
Document Type and Number:
WIPO Patent Application WO2002007250
Kind Code:
A3
Abstract:
The invention relates to a multi-polar band pass filter based on a group of dielectric mode resonators which are placed in a metal housing and coupled to each other. The dual metal housing comprises metal walls. Said metal walls effect a coupling between the dual mode resonators in such a way that one positive forward coupling between the respective neighbouring pairs of resonators and a positive and a negative coupling within each pair of resonators arises.
