Title:
FILTER AND COMMUNICATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/199784
Kind Code:
A1
Abstract:
In this filter, a filter element is included in a signal path extending from an input side to an output side. A first resonator connects: a site, on the signal path, which electrically serves as an input side with respect to the filter element; and a reference potential part. The first resonator has a first inductor. A second resonator connects a site, on the signal path, which electrically serves as an output side with respect to the filter element, and the reference potential part, and has a second inductor. A third inductor is magnetically coupled with the first inductor. A fourth inductor is magnetically coupled with the second inductor. The third inductor and the fourth inductor each have one end side separately connected to the reference potential part, have portions, on the side electrically opposite the side connected to the reference potential section, connected to each other, and are electrically disconnected from the signal path.
