Abstract
The present disclosure provides for a phase shifter having at least one phase shift section. The phase shift section includes an input port for receiving an incoming radio frequency signal, an output port for transmitting an outgoing radio frequency signal, an input junction coupled to the input port, an output junction coupled to the output port, and a plurality of transmission lines. The input junction includes a first plurality of cantilever type switches, and the output junction includes a second plurality of cantilever type switches. Each transmission line connects one of the first plurality of cantilever type switches to a corresponding one of the second plurality of cantilever type switches. The first plurality of cantilever type switches, the second plurality of cantilever type switches, and the plurality of transmission lines are formed in a coplanar waveguide.
