Patent ID: 8605396

Claim:
A circuit comprising: a Radio Frequency (RF) input; a first inductor connected in series between the RF input and RF front end circuitry; a first diode connected to the RF input and to the first inductor and to a power line; and a second diode connected to the RF input and to the first inductor and to a complementary power line, the second diode connected to the complementary power line through a second inductor and connected to a node between the first inductor and the RF front end circuitry, in which the first and second diodes are reverse biased during normal operation of the RF front end circuitry, and in which the first and second diodes provide respective first and second electrostatic discharge (ESD) current paths away from the RF front-end circuitry during an ESD event, in which the first diode provides the first ESD current path from the RF input to the power line, and wherein the second diode provides the second ESD current path from the complementary power line through the second inductor to the RF input.
