Patent ID: 7952845

Claim:
A V-band radio frequency (RF) electrostatic discharge (ESD) protection circuit adapted for discharging static electricity input from a RF pad, the V-band RF ESD protection circuit comprising: at least one first meander inductor; at least one second meander inductor; at least one first ESD member; and at least one second ESD member; wherein the first meander inductor and the second meander inductor are respectively disposed in two metal layers that are located at a top of a substrate, a first terminal of the first meander inductor is connected with a cathode of the corresponding first ESD member in series, a first terminal of the second meander inductor is connected with an anode of the corresponding second ESD member in series, a second terminal of the first meander inductor and a second terminal of the corresponding second meander inductor are connected to the RF pad in parallel, the RF pad is connected to a low-noise amplifier, the low-noise amplifier generates a low-noise amplified signal and transmits the low-noise amplified signal to a core circuit, an anode of the first ESD member is grounded, and a voltage is applied to a cathode of the second ESD member.
