Abstract

The invention discloses a radio frequency circuit and electronic equipment, and belongs to the technical field of electronic circuits. The dual-connection networking radio frequency circuit comprises a first radio frequency transceiving module, a first notch network, a first antenna, a second radio frequency transceiving module, a second notch network and a second antenna, wherein the first notch network is connected between the first radio frequency transceiver module and the first antenna, and the first notch network is used for suppressing a radio frequency signal of a frequency band corresponding to the second radio frequency transceiver module; and the second notch network is connected between the second radio frequency transceiver module and the second antenna, and the second notch network is used for suppressing a radio frequency signal of a frequency band corresponding to the first radio frequency transceiver module. The circuit can solve the problem of interference between radio frequency signals of different frequency bands under non-independent networking.

Description

technical field [0001] The application belongs to the technical field of electronic circuits, and in particular relates to a radio frequency circuit and an electronic device. Background technique [0002] The network architecture, technology and frequency based on LTE (Long Term Evolution, long-term evolution) can no longer meet the requirements of higher speed, lower delay, and larger capacity. Therefore, the fifth generation of mobile communication technology (5G for short) came into being pregnancy. [0003] At present, 5G communication has two modes of independent networking (Standalone, SA) and non-independent networking (Non-Standalone, NSA). In the non-independent networking, the terminal and the base station communicate through LTE and NR dual connections, that is, LTE and NR work at the same time. On this basis, the terminal is equipped with a 4G antenna and a 5G antenna. However, the size of the antenna is limited by the size of the terminal, and there are situa...
