MINIATURE BAND PASS FILTER OF CHANNELS OF ULTRA-WIDEBAND USING MULTIPLE RINGS GENERATING PHASE DIFFERENCES

摘要

An ultra-wideband small channel bandpass filter having a multiple ring structure for guiding a phase path difference includes an input coupling line for causing electronic coupling to an input port for receiving a radio frequency signal and an output port for outputting a radio frequency signal in a passband, An input coupling line and an output coupling line are connected through a main transmission path causing resonance and an input coupling line and an output coupling line are connected through a bypass line to a different path from the main transmission line.
