Abstract

A millimeter wave RF phase shifter includes an input and an output. The RF phase shifter further includes a transmission line coupled to the input. The transmission line can include a plurality of taps. The RF phase shifter can further include a plurality of switching devices. Each switching device can be coupled between the output and a corresponding tap of the plurality of taps. The RF phase shifter can include a control device operatively coupled to the plurality of switching devices. The control device can be configured to control operation of the plurality of switching devices to selectively couple one of the plurality of taps to the output to control a phase shift of a RF signal propagating on the transmission line.
