Abstract
The present invention provides a flexible mechanical bridge over a microstrip on a substrate, which utilizes an electromagnetic field increase, as generated by temporary power surge to shunt harmful power away from a MMIC system. The invention includes a power limiter which includes an airbridge , preferably in the form of an electrically conductive strip with ground contacts and formed thereon. The ground contacts and are electrically connected, through via holes and respectively, to a metallization layer formed on the bottom side of a substrate . The air bridge is designed such that it traverses an electrically conductive microstrip forming an air gap between the air bridge and the electrically conductive microstrip . When there is a power surge the air bridge , will flex to cause an electrical connection with the microstrip , thereby directing the unwanted signal through the ground contacts and and the via holes and to the metallization layer
