Abstract

Embodiments of the application disclose a protection circuit, a radio frequency circuit, and electronic equipment. The protection circuit comprises a front-end interface, a back-end circuit and a capacitor, the capacitor is arranged between the front-end interface and the back-end circuit in parallel, one terminal of the capacitor is separately connected with the front-end interface and the rear-end circuit, the other end of the capacitor is connected to the ground, and the capacitor is used for discharging an electrostatic current transmitted by the front-end interface. According to the scheme, the electrostatic discharging capability of the electronic equipment can be increased, the damage to the back-end circuit and the interference with the back-end circuit by static electricity are reduced, and effective electrostatic protection is provided for the electronic equipment.

Description

Technical field [0001] This application relates to the technical field of terminals, and in particular to a protection circuit, a radio frequency circuit, and electronic equipment. Background technique [0002] Electrostatic Discharge (ESD) is a very common natural phenomenon in life. When different materials are in contact with each other, a certain amount of charge may accumulate on the surface, and electrostatic discharge of up to ten thousand volts may occur when encountering other objects. Voltage. Electronic equipment may suffer from this electromagnetic energy damage. With the widespread application of microelectronic components, ESD issues have also been paid more attention. [0003] At present, electronic devices such as mobile phones, laptops, and tablet computers are all very sophisticated electronic devices. For example, nowadays mobile phones are becoming smaller and thinner, and the integration of internal electronic components is also increasing. During the use o...
