Abstract:
Provided are a bandpass filter and a radio communication module and a radio communication device using the same. The bandpass filter includes: a first and a second grounding electrode arranged on the upper and the lower surface of a layered body; first resonance electrodes and second resonance electrodes arranged to orthogonally intersect the first resonance electrodes; a first input coupling electrode opposing to the first resonance electrode of the input stage and a second input coupling electrode connected thereto and opposing to the second resonance electrode of the input stage; a first output coupling electrode opposing to the first resonance electrode of the output stage and a second output coupling electrode connected thereto and opposing to the second resonance electrode of the output stage.
