A V-band radio frequency (RF) electrostatic discharge (ESD) protection circuit uses meander inductors and diodes connecting in series to provide ESD protection. When operated in low frequency, the static electricity input from a RF pad may discharge to ground or to a voltage VDD through the meander inductor and the diode, so that a core circuit is not damaged by ESD. When operated in high frequency, the high frequency stray effect of the core circuit is substantially reduced due to impedance isolation generated by the meander inductors. Therefore, a low-noised amplifier (LNA) can receive an accurate high frequency input signal.
