Title:
RADIO FREQUENCY FRONT-END MODULE AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/001458
Kind Code:
A1
Abstract:
The present application discloses a radio frequency front-end module and an electronic device. The radio frequency front-end module comprises a first balun, a differential amplification circuit connected to the first balun, and a bias circuit connected to an input end of the differential amplification circuit, the bias circuit being disposed in a magnetic core region formed by winding of a coil of the first balun. The bias circuit is disposed in the magnetic core region formed by winding of the coil of the first balun, so that the overall area occupied by the bias circuit and the first balun is small, thereby satisfying integration and miniaturization requirements.
