Title:
HIGH-FREQUENCY MODULE AND COMMUNICATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/009748
Kind Code:
A1
Abstract:
The present invention limits deterioration of isolation when performing transmission of both a first transmission signal and a second transmission signal by simultaneous communication. A high-frequency module (1) is provided with a first transformer (120) and a second transformer (220). The first transformer (120) is included in a first differential power amplifier (13) for amplifying a first transmission signal. The second transformer (220) is included in a second differential power amplifier (15) for amplifying a second transmission signal which is communicated simultaneously with the first transmission signal. The direction of a magnetic flux generated in the first transformer (120) and the direction of a magnetic flux generated in the second transformer (220) are different from each other.
