Radio frequency control circuit and electronic equipment

Abstract

The embodiment of the invention provides a radio frequency control circuit and electronic equipment. The radio frequency control circuit comprises a baseband controller, a wireless fidelity link and aharmonic attenuation module. The wireless fidelity link comprises a receiving sub-link, a transmitting sub-link and a first selection switch, and the receiving sub-link and the transmitting sub-linkare connected with a first end of the first selection switch; the harmonic attenuation module is connected with the wireless fidelity link; the harmonic attenuation module and the wireless fidelity link are respectively connected with the baseband controller; the baseband controller is used for controlling the harmonic attenuation module and the wireless fidelity link to be connected or disconnected according to the on-off state of the first selection switch and the transmitting sub-link, the transmitting sub-link is used for transmitting a radio frequency signal generated by the baseband controller, and the harmonic attenuation module is used for attenuating second harmonics in the radio frequency signal. In the embodiment of the invention, the wireless fidelity link and the 5G link can coexist to work, the frequency of the 5G link does not need to be reduced, and the user experience is improved.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a radio frequency control circuit and electronic equipment. Background technique [0002] With the development of communication technology, radio frequency devices in electronic equipment need to perform radio frequency communication at higher and higher frequencies. During radio frequency communication, different radio frequency signals are often easily interfered with each other. For example, when the Wireless-Fidelity (Wi-Fi) 2.4G link in electronic equipment passes through nonlinear devices such as power amplifiers when transmitting radio frequency signals, it is easy to generate second harmonics, and the frequency band of the second harmonics It is 4804-4964MHz, and the frequency band of the 5G link in the electronic equipment includes the sub-band n79, and the frequency band of the sub-band n79 is 4400-5000MHz. At this time, the frequency band of the second harmonic ...
