ABSTRACT:
A signal equalizer that employs micro-electromechanical machine devices for the tap weight controllers. The equalizer includes a substrate on which is formed a forward transmission line rail and a return transmission line rail. A cantilever stanchion is also formed on the substrate that runs parallel with the transmission line rails. A series of spaced apart cantilevers are pivotally mounted to the cantilever stanchion, and extend over the transmission line rails to define a gap therebetween. A weight tap line is coupled to each cantilever, and is responsive to a DC weight signal that controls the position of the cantilever to set the gap between the cantilever and the transmission line rails. A distorted signal is coupled from the forward transmission line rail to the return transmission line rail through the cantilevers.
