Abstract: The present disclosure provides for a microelectromechanical switch including a first port (e.g., input port), one or more second ports (e.g., output ports), a cantilever beam, and a mechanical spring connected to the cantilever beam for providing a mechanical force to move the cantilever beam. The cantilever beam extends from a first end, which is in contact with either the first port or one of the second ports, to a second end that is switchably connectable to the other of the first port or said one of the second ports. The first and second ports and cantilever beam may be formed in a coplanar waveguide.

Abstract: The present disclosure is directed to a balun circuit adapted to operate at a frequency of between about 5 GHz to about 110 GHz. The balun circuit includes first and second output striplines and an input stripline formed on a first surface of the substrate, and a slotline formed on a second surface of the substrate opposite the first surface. The slotline has first and second ends, the first end overlapping the first output stripline and the second end overlapping the second output stripline, and the input stripline overlapping the slotline midway between the first end and the second end.
