ABSTRACT:
A modulator includes a micro-electromechanical resonator device configured to receive an input signal and generate two output signals in response thereto, wherein the two signals having a predetermined phase relationship therebetween. The modulator further includes a switching system configured to selectively pass one of the two signals to an output of the modulator in an alternating fashion in response to phase modulation data.
