Abstract:
1. A surface acoustic wave (SAW) device-based communications system, comprising: a first SAW device including a first transducer and reflectors in a first acoustic path providing a first orthogonal frequency code (OFC), at least a second SAW device including a second transducer and reflectors in a second acoustic path providing a second OFC different from the first OFC; a magnetic switch having a first input port, a second input port, and an output port, the first input port connected to an input port of the first transducer, the second input port connected to an input port of the second transducer; and an external magnetic field source for switching the magnetic switch, wherein in one switch state the first OFC appears at the output port and in another switch state the second OFC appear at the output port.
