Abstract

The embodiment of the application discloses a protection circuit, a radio frequency circuit and electronic equipment. The protection circuit comprises a front-end interface, a rear-end circuit and aninductor; the inductor is arranged in parallel between the front-end interface and the rear-end circuit; one end of the inductor is respectively connected with the front-end interface and the rear-endcircuit, and the other end of the inductor is grounded; and the inductor is used for carrying out discharging on an electrostatic current transmitted by the front-end interface. According to the scheme, electrostatic discharging capacity of the electronic equipment can be improved, damage and interference of static electricity to the rear-end circuit are reduced, and effective electrostatic protection is provided for the electronic equipment.

Description

technical field [0001] The present application relates to the technical field of terminals, in particular to a protection circuit, a radio frequency circuit and electronic equipment. Background technique [0002] Electrostatic discharge (Electro Static Discharge, ESD) is a very common natural phenomenon in life. When different materials and materials come into contact with each other, a certain amount of charge may accumulate on the surface. When encountering other objects, it may generate an electrostatic discharge of up to ten thousand volts. Voltage. Electronic devices can be damaged by this electromagnetic energy. With the widespread application of microelectronic components, more attention has been paid to ESD issues. [0003] At present, electronic devices such as mobile phones, laptops, and tablet computers are very sophisticated electronic devices. For example, mobile phones are becoming smaller and thinner, and the integration of electronic components inside is g...
