Abstract

The embodiment of the application discloses an electrostatic protection device, a radio frequency circuit, and an electronic device. The electrostatic protection device comprises a front-end interface, an electrostatic protection circuit and a rear-end circuit. The electrostatic protection circuit is arranged between the front-end interface and the rear-end circuit; and one end of the electrostatic protection circuit is connected with the front-end interface and the other end is connected with the rear-end circuit. The electrostatic protection circuit formed by at least one resistor is used for discharging electrostatic currents transmitted by the front-end interface. Therefore, electrostatic protection on an electronic device is realized.

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 equipment can be damaged by this electromagnetic energy at any time. 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 elect...
