Title:
BANDPASS FILTER
Document Type and Number:
WIPO Patent Application WO/2019/097774
Kind Code:
A1
Abstract:
The purpose of the present invention is to make the frequency characteristics of a bandpass filter approach desired frequency characteristics. A first LC parallel resonator (11) is electrically connected to a first terminal (P10) at a first connection point (114). A second LC parallel resonator (14) is electrically connected to a second terminal (P100) at a second connection point (117). A first capacitor (111) and a second capacitor (112) are connected in series between the first connection point (114) and the second connection point (117). A third capacitor (113) is connected between a ground point (GND) and a third connection point (118) between the first capacitor (111) and the second capacitor (112).
