Abstract

Embodiments of the invention disclose an electrostatic protection apparatus, a radio frequency circuit and electronic equipment. The electrostatic protection apparatus comprises a front end interface,an electrostatic protection circuit and a back end circuit; the electrostatic protection circuit is positioned between the front end interface and the back end circuit; one end of the electrostatic protection circuit is connected with the front end interface while the other end is connected with the back end circuit; and the electrostatic protection circuit consists of an electrostatic dischargecircuit and a <pi>-shaped filtering circuit in connection, and is used for performing discharging of the electrostatic current transmitted by the front end interface. By virtue of the scheme, the electrostatic discharge capability of the electronic equipment can be improved, damage and interference to the back end circuit from electrostatic can be lowered, and effective electrostatic protection isprovided for the electronic equipment.

Description

technical field [0001] The present application relates to the field of terminal technology, 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...
