Abstract
A relay for wideband signals is provided having a rotor which includes a permanent magnet structure, an armature, and a microstrip pattern for selectively engaging microstrip patterns on a substrate and having a stator which includes an electromagnet. To minimize wear, while maintaining high frequency performance, the rotor is raised, rotated, and lowered by a stator or electromagnet onto the new position relative to the substrate microstrip pattern. In a first stable state the electromagnet is inactive and the rotor engages the substrate microstrip pattern in a first position. To place the relay in a second stable state, the electromagnet is energized which simultaneously attracts the armature, raising the rotor, as well as repulsing the permanent magnet structure. The rotor then rotates to the desired second position and the electromagnet is inactivated. The rotor then lowers and engages the substrate microstrip pattern in a second position.
