Title:
HIGH FREQUENCY MODULE AND COMMUNICATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/276871
Kind Code:
A1
Abstract:
The present invention mitigates characteristics degradation during simultaneous communication. In a high frequency module (500), a plurality of filters are connected to an antenna terminal (T1) via a switch (7). The plurality of filters include a first filter having a passband including the frequency band of a first communication band, and a second filter having a passband including the frequency band of a second communication band in which communication can be performed simultaneously with the first communication band. A first electronic component (E1) having the first filter and a second antenna-end resonator (24A) of the second filter is disposed on a first main surface (101) of a mounting substrate (100). A second electronic component (E2) having at least one second elastic wave resonator other than the second antenna-end resonator (24A) of the second filter is disposed on the first main surface (101) of the mounting substrate (100). The distance between the first electronic component (E1) and the switch (7) is less than the distance between the second electronic component (E2) and the switch (7).
