Abstract: A tunable passband filter including a signal input port for receiving an input radio frequency (RF) signal, a signal output port for transmitting a filtered output RF signal, a first high-pass section having a first tunable microelectromechanical system (MEMS) switch array to receive the input RF signal from the signal input port, a second high-pass section having a second tunable MEMS switch array to transmit the output RF signal to the signal output port, and a low pass section operatively coupled between the first high-pass section and the second high-pass section, and having each of a first tunable MEMS bridge array, a second tunable MEMS bridge array, and a high impedance line. The tunable passband filter is configured to filter the input RF signal to yield the filtered output RF signal.

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.
