Abstract
A miniaturized electrostatic discharge (ESD) protection circuit designed for millimeter wave electrical elements, wherein the ESD protection circuit is fabricated on a multilayer substrate. The ESD protection circuit comprises a metal line being connected at one end to a ground and at other end to a connective strip, wherein a length of the metal line is a maximum length that achieves a resistance value defined for the ESD protection circuit and a width of the metal line is set to a maximum width allowed for the multilayer substrate, wherein the metal line introduces a inductance value into the ESD protection circuit; and a capacitor being connected in parallel to the metal line and having a capacitance value resonating the metal line at an operating frequency band, thereby the ESD protection circuit shunts ESD pulses to the ground and passes signals at the operating frequency band.
