Document Type and Number:
WIPO Patent Application WO/2024/001132
Kind Code:
A1
Abstract:
Disclosed in the present application are a radio-frequency front-end device and an electronic device. The radio-frequency front-end device has an LB PA, an MB PA, an HB PA, a filter, an LNA and a switch integrated therein, simultaneously supports low, medium, and high-frequency bands (LMH bands), and supports an M+H dual-transmission function; moreover, an L+M dual-transmission function and an L+H dual-transmission function are realized by means of reusing an internal or external duplexer of the radio-frequency front-end device, thereby better reducing the occupied area of a PCB, and decreasing the cost of the electronic device.
