Embodiment Construction

[0040] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0041] It can be understood that the terms "first", "second" and the like used in this application may be used to describe various elements herein, but these elements are not limited by these terms. These terms are only used to distinguish one element from another element. For example, a first client could be termed a second client, and, similarly, a second client could be termed a first client, without departing from the scope of the present application. Both the first client and the second client are clients, but they are not the same client.

Abstract

The invention relates to a radio frequency system and communication equipment. The radio frequency system comprises a radio frequency transceiver, a first transceiving circuit, a second transceiving circuit and a diversity receiving circuit, wherein the first transceiving circuit and the diversity receiving circuit are configured to be connected with a first antenna and a second antenna in a switchable mode; the second transceiving circuit is configured to be connected with a third antenna; the diversity receiving circuit is configured to be connected with a fourth antenna; the first transceiving circuit supports emission and main set receiving of low-frequency signals; the second transceiving circuit supports emission and main set MIMO receiving of the low-frequency signals; and the diversity receiving circuit supports diversity receiving and diversity MIMO receiving of the low-frequency signals. Therefore, the radio frequency system can support double-path emission and a 4 * 4 MIMO function of the low-frequency signals; and when the radio frequency system is located in weak signal environments such as an edge of a community, a deep position of a building and an elevator, compared with a radio frequency system which can only support 2 * 2 MIMO receiving of the low-frequency signals in a related technology, the radio frequency system can double diversity gains, can double a coverage distance, and can greatly improve the receiving performance.

Description

technical field [0001] The present application relates to the technical field of antennas, 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. When the traditional radio frequency system is in areas with poor signals such as the edge of the cell, deep in the building or elevators, the reception performance of the 5G low-frequency signal (for example, the N28 frequency band signal) is poor. Contents of the invention [0003] Embodiments of the present application provide a radio frequency system and communication e...
