  • Abstract
    A novel MEMS-based binary phase shift keying direct-digital modulator operating at a carrier frequency of 2.4 GHz is presented. The circuit is composed of a rat-race coupler and a single-pole double-throw MEMS switch controlled by a digital baseband signal. The coupler divides the input waveform into two signals that are 180° out of phase and the MEMS switch is used to select between these two signals. This circuit has been experimentally verified and results are reported.
