Abstract

The invention provides a radio frequency system and a communication device, in the radio frequency system, a radio frequency transceiver, a transmission amplification circuit, a filter circuit and a first antenna can form a transmission path to realize transmission processing of a preset low-frequency signal; the radio frequency transceiver, the emission amplification circuit, the filter circuit and the second antenna can form another emission path to realize emission processing of the preset low-frequency signal; the first antenna, the filter circuit and the first receiving circuit can form a first receiving path so as to support receiving of a preset low-frequency signal; the second antenna, the filter circuit and the first receiving circuit can form a second receiving path so as to support receiving of a preset low-frequency signal; the third antenna and the second receiving circuit can form a third receiving path to support receiving of preset low-frequency signals, and the fourth antenna and the second receiving circuit can form a fourth receiving path to support receiving of the preset low-frequency signals, so that the radio frequency system supports double-path emission of the preset low-frequency signals and a downlink 4 * 4 MIMO receiving function.

Description

technical field [0001] The present application relates to the field of radio frequency technology, in particular to a radio frequency system and communication equipment. Background technique [0002] With the development and progress of technology, mobile communication technology is gradually applied to communication devices, such as mobile phones. With the development and progress of technology, 5G mobile communication technology has gradually begun to be applied to electronic devices. The communication frequency of 5G mobile communication technology is higher than that of 4G mobile communication technology. Traditional radio frequency systems have poor receiving and transmitting performance for 5G low-frequency signals (for example, N28 frequency band signals) in areas with poor signals such as the edge of a cell, deep in a building, or an elevator. Contents of the invention [0003] Embodiments of the present application provide a radio frequency system and communicat...
