Patent ID: 7212801

Claim:
A wireless communication device comprising: a case; an antenna; and a radio at least partially contained in the case and comprising: a baseband processor; an RE front end circuit formed in an integrated circuit and having an antenna interface; and an electrostatic discharge circuit formed in the integrated circuit and communicatively coupled between the antenna and the antenna interface of the RF front end circuit, wherein the elecirostatic discharge circuit is operable to protect the RF front end circuit from an over-voltage condition and wherein the electrostatic discharge circuit provides a matched impedance to the antenna, the electrostatic discharge circuit comprising: at least one shunt circuit operable to shunt current related to an over-voltage condition, the at least one shunt circuit including an over voltage clamp and an impedance matching shunt element; and at least one series element operably coupled to the at least one shunt element including at least one impedance matching series element.
