Title:
RADIO FREQUENCY SYSTEM AND COMMUNICATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/016199
Kind Code:
A1
Abstract:
A radio frequency system, which comprises a power supply module (110) and an amplification module (130). The amplification module (130) comprises a first amplification unit (131) which amplifies a received low-frequency signal; a second amplification unit (132) which amplifies a received intermediate-frequency signal; a third amplification unit (133) which amplifies a received first high-frequency signal; and a fourth amplification unit (134) which amplifies a received second high-frequency signal. The frequency of the second high-frequency signal is higher than the frequency of the first high-frequency signal, and the radio frequency system is used for selecting and outputting a radio frequency signal processed by any of the amplification units.
