Description

technical field

[0001] The present application relates to the technical field of terminals, in particular to an electrostatic protection device, 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 componen...
