Claim Text:
1. An ESD protection circuit cooperated with a high-frequency circuit, comprising: a silicon-controlled rectifier element formed by the sequential connection of a first P-type semiconductor material, a first N-type semiconductor material, a second P-type semiconductor material and a second N-type semiconductor material, and having a first end electrically coupled with the first P-type semiconductor material and a second end electrically coupled with the second N-type semiconductor material, wherein the first end is an anode of the silicon-controlled rectifier element and the second end is a cathode of the silicon-controlled rectifier element; an inductive element, wherein one end of the inductive element is electrically coupled with the first end and the other end of the inductive element is electrically coupled with the first N-type semiconductor material, or one end of the inductive element is electrically coupled with the second end and the other end of the inductive element is electrically coupled with the second P-type semiconductor material; and a trigger unit, wherein one end of the trigger unit is electrically coupled to the first N-type semiconductor material and the other end of the trigger unit is electrically coupled to the second P-type semiconductor material.
