Abstract

Embodiments of the present invention provide a radio frequency control circuit and electronic equipment. The radio frequency control circuit includes: a baseband controller, a wireless fidelity link, and a harmonic attenuation module; wherein, the wireless fidelity link includes a receiving sub-link, a transmitting sub-link and a first selection switch, and the receiving sub-link, the transmitting sub-link The link is respectively connected to the first end of the first selection switch; the harmonic attenuation module is connected to the wireless fidelity link; the harmonic attenuation module and the wireless fidelity link are respectively connected to the baseband controller, and the baseband controller is used for The on-off state of the first selection switch and the transmitting sub-link controls the connection or disconnection of the harmonic attenuation module and the wireless fidelity link, wherein the transmitting sub-link is used to transmit the radio frequency signal generated by the baseband controller, and the harmonic attenuation module The wave attenuation module is used to attenuate the second harmonic in the radio frequency signal. In the embodiment of the present invention, the Wi-Fi link and the 5G link can coexist and work without reducing the frequency of the 5G link, which improves user experience.

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 ...
