Paper Abstract

We describe in this paper the architecture of a multiphase sinewave generator based on Direct Digital Synthesis techniques. This generator is used as the electric command of a 2?2 switch with an acousto-optic cell architecture using planar phased array piezoelectric transducers. This generator is able to adjust precisely the frequency and the phase of the RF signal on each transducer, and so to improve the switch performance.
