Abstract:
The unwanted double transit echo (DTE) of a passive wireless reflective delay-line SAW device is efficiently suppressed by using a 3rd harmonic-operating single phase unidirectional transducer (SPUDT). The frequency dependence of the DTE suppression level is shown by comparing devices with a Walsh-Hadamard-like reflector and a single-frequency Bragg reflector. A tunable dipole antenna is used to precisely tune the impedance required for the echo suppression.
