Title:
HIGH-FREQUENCY MODULE AND COMMUNICATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/002238
Kind Code:
A1
Abstract:
The present invention inhibits a harmonic component of a signal passing through a relatively low-frequency passband filter from adversely affecting the filter characteristics of a relatively high-frequency passband filter. A high-frequency module (1) is provided with a first switch (4), an attenuating filter (3), and a plurality of passband filters (12A to 12C, 22A to 22C). The first switch (4) is capable of connecting a common terminal (40) with selected terminals (41, 42) among a plurality of selected terminals (41 to 43) simultaneously. The plurality of passband filters (12A to 12C, 22A to 22C) include a first passband filter (22A) and a second passband filter (22B). The attenuating filter (3) includes a reactance element of at least one of an inductive element and a capacitive element. In the high-frequency module (1), the reactance element is adjacent to at least one of the plurality of passband filters (12A to 12C, 22A to 22C).
