Abstract

An embodiment of the invention discloses an electrostatic protection device, a radio frequency circuit and electronic equipment. The electrostatic protection device comprises a front end interface, an electrostatic protection circuit and a rear end circuit. The electrostatic protection circuit is located between the front end interface and the rear end circuit. One end of the electrostatic protection circuit is connected to the front end interface and the other end is connected to the rear end circuit. The electrostatic protection circuit is formed by an electrostatic discharge circuit and a T-shaped filter circuit which are connected together and is used for discharging a static current transmitted by the front end interface. In the scheme, an electrostatic discharge capacity of the electronic equipment can be increased, damages and an 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 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...
