Title:
HIGH FREQUENCY MODULE AND COMMUNICATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/131223
Kind Code:
A1
Abstract:
Provided are a high frequency module and a communication device wherein in a case of performing simultaneous communications using a plurality of frequency bands, it can be achieved to increase the degree of flexibility in layout design of　implementation boards, while suppressing the degradation of communication quality. A high frequency module (1) comprises an antenna terminal (2), a transmission filter (3), a reception filter (a first reception filter 4), a transfer filter (a second reception filter 5), a switch (6), and a reactance element (a capacitor 17). The transmission filter (3) passes therethrough a first transmission signal of a first passband defined according to a standard. The reception filter passes therethrough a first received signal of the first passband. The transfer filter passes therethrough a communication signal of a second passband. The switch (6) can simultaneously connect with the antenna terminal (2), with the transmission filter (3) or the reception filter, with the transfer filter, and with the reactance element. The reactance element is configured together with the switch (6) in a single chip.
