Abstract

The invention provides a radio frequency system and communication equipment, and the system comprises a radio frequency transceiver; the power amplification module is used for supporting power amplification processing of a preset low-frequency signal; the filtering gating module is respectively connected with the power amplification module and the first antenna and is used for filtering the received preset low-frequency signal; the first receiving circuit is respectively connected with the radio frequency transceiver and the filtering gating module and is used for receiving the preset low-frequency signal filtered by the filtering gating module so as to support receiving processing of the received preset low-frequency signal, and the first receiving circuit is also used for supporting receiving processing of the preset low-frequency signal received by the second antenna; and the second receiving circuit is used for supporting the receiving processing of the preset low-frequency signal received by the third antenna and supporting the receiving processing of the preset low-frequency signal received by the fourth antenna, so that the 4 * 4 MIMO receiving of the preset low-frequency signal can be realized, and the receiving performance is better.

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...
