Abstract

The embodiment of the invention discloses an electro static protection apparatus, a radio-frequency circuit and an electronic device. The electro static protection apparatus comprises a front-end interface, an electro static protection circuit and a rear-end circuit; the electro static protection circuit is positioned between the front-end interface and the rear-end circuit; one end of the electro static protection circuit is connected with the front-end interface, and the other end of the electro static protection circuit is connected with the rear-end circuit; and the electro static protection circuit consists of an electro static discharge circuit and a resistor by connection, and is used for discharging an electro static current transmitted by the front-end interface. The electro static protection apparatus provided by the invention can provide effective electro static protection for the electronic device.

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...
