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

Abstract

The application discloses a radio frequency circuit and electronic equipment. The radio frequency circuit includes: 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; wherein, the first An antenna, a second antenna, a third antenna, and a fourth antenna are respectively connected to 4 T ports of the 4P4T selector switch; wherein, the first combiner includes a low-pass port, a band-pass port and a common port, and the first combiner The passband of the low-pass port is lower than the passband of the band-pass port; wherein, the low-pass port of the first combiner is connected to the first LTE medium / low frequency signal line, and the band-pass ports of the first combiner are respectively connected to A first NR signal line; wherein, the common end of the first combiner is connected to the first P port of the 4P4T selection switch. This application reduces design complexity by sharing 5G NR and 4G antennas.

Description

technical field [0001] The present application belongs to the technical field of radio frequency architecture of non-independent networking antennas, and in particular relates to a radio frequency circuit and electronic equipment. Background technique [0002] In related technologies, 5G networks will adopt two networking methods in the process of development and construction: 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. 4G LTE and 5G NR (5G New Radio, 5G new air interface) can communica...
