Radio frequency circuit and electronic equipment

Abstract

The invention discloses a radio frequency circuit and electronic equipment. The radio frequency circuit comprises a first NR signal line, a first LTE medium / low frequency signal line, a first antenna,a second antenna, a third antenna, a fourth antenna, a 4P4T selection switch and a first combiner. The first antenna, the second antenna, the third antenna and the fourth antenna are respectively connected with four T ports of the 4P4T selection switch; the first combiner comprises a low-pass port, a band-pass port and a common port, and the pass band of the low-pass port of the first combiner islower than the pass band of the band-pass port; a low-pass port of the first combiner is connected to a first LTE medium / low-frequency signal line, and band-pass ports of the first combiner are respectively connected to a first NR signal line; and the common end of the first combiner is connected with the first P port of the 4P4T selection switch. By sharing the 5GNR antenna and the 4G antenna, the design complexity is reduced.

Description

technical field [0001] The application belongs to the technical field of radio frequency architecture of non-independent networking antennas, and specifically relates to a radio frequency circuit and electronic equipment. Background technique [0002] In related technologies, two networking methods will be adopted in the development and construction of 5G networks: non-independent networking (NSA: Non-standalone) and independent networking (SA: Standalone). The networking architecture that NSA usually refers to is: on the wireless side, 4G base stations and 5G base stations coexist; on the core network side, 4G core network or 5G core network is used. The networking architecture that SA usually refers to is: on the wireless side, a 5G base station is used, and on the core network side, a 5G core network is used. [0003] In the NSA mode, the following technical requirements are met: [0004] A. 4GLTE and 5G NR (5GNewRadio, 5G new air interface) can communicate based on dua...

AI Technical Summary

Problems solved by technology

On the one hand, mobile communication devices such as mobile phones are limited in size and can accommodate a limited number of antennas; on the other hand, there are too many antennas in mobile communication devices, and the antennas will affect each other, which increases the difficulty of antenna design

In addition, mobile communication devices may also contain antennas for WIFI, GPS, etc., which further increases the design difficulty
