Embodiment Construction

[0027] In order to make the objects, technical solutions and advantages of the present application, the present application will be described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are intended to explain the present application and is not intended to limit the present application.

[0028] It will be appreciated that the terms "first", "second", and the like as used herein can be used herein to describe various elements, but these components are not limited by these terms. These terms are only used to distinguish the first element from another element. For example, the first antenna can be referred to as a second antenna without departing from the scope of the present application, and the second antenna can be referred to as a first antenna. Both the first antenna and the second antenna are antennas, but they are not the same antenna.

[0029] Moreover, the term "first", "sec...

Abstract

The invention relates to a radio frequency system and communication equipment, the radio frequency system comprises a radio frequency transceiver and a radio frequency transmit-receive circuit, the radio frequency transmit-receive circuit is connected with the radio frequency transceiver, the radio frequency transmit-receive circuit is configured with a first receiving path, a second receiving path, a third receiving path and a fourth receiving path, the first receiving path is connected with the second receiving path, and the third receiving path is connected with the fourth receiving path. The main set is configured to support main set receiving of low-frequency signals; the second receiving path is configured to be used for diversity reception of the low-frequency signals; the third receiving path is configured to be used for supporting MIMO receiving of the low-frequency signal; and the fourth receiving path is configured to be used for supporting MIMO receiving of the low-frequency signals, and can realize a 4 * 4 MIMO receiving function of the low-frequency signals so as to improve the receiving performance of the low-frequency signals.

Description

Technical field [0001] The present application relates to the field of antenna, in particular to a radio frequency system and a communication device. Background technique [0002] With the development and progress of technology, mobile communication technology gradually begins to communicate equipment, such as mobile phones. With the development and progress of technology, 5G mobile communication technologies gradually begin to be applied to electronic devices. 5G mobile communication technology communication frequency is more frequent than 4G mobile communication technology. The conventional radio frequency system is in a region where the cell edge, the building is depth, or the elevator is poor, and the reception performance of the 5G low frequency signal (eg, the N28 band signal) is poor. Inventive content [0003] The present application embodiment provides a radio frequency system and a communication device, which can improve the reception performance of the low frequency s...
