HIGH REJECTION BAND-STOP FILTER AND DIPLEXER USING SUCH FILTERS
摘要:
The present invention relates to a high rejection stop band filter and a diplexer using such filters.The stop band filter comprises on a substrate with a ground plane, a transmission line extending between an input and an output and comprises several resonators formed of “stubs” in printed open circuit embedded into the transmission line, the resonators being positioned in parallel together and interconnected in series in the same direction or head to tail.The filters are particularly useful in mobile devices operating in two concurrent frequency bands.
