Description
technical field [0001] The present disclosure relates to the technical field of electronic devices, and in particular, to a radio frequency module, a control method thereof, and an electronic device. Background technique [0002] With the development and progress of technology, more and more radio frequency bands are used in the communication of electronic devices. In a radio frequency module of an electronic device, the radio frequency signal is usually amplified by a power amplifier. As more and more RF frequency bands are required for electronic equipment to work, the number of power amplifiers and power modules in the RF module also increases. More power amplifiers and power modules will increase the cost of electronic equipment, and is not conducive to electronic equipment. Thinning of the device. [0003] It should be noted that the information disclosed in the above Background section is only for enhancement of understanding of the background of the present disclosu...
