A SAW delay line is modelled with Finite element modelling technique upon A Gallium arsenide substrate and this device is modelled and simulated around center frequency of 1.5GHz that is used in different electronic devices at a high frequency range. A five periodic cycles of output voltage is simulated and monitored at output port of delay line while applying a sine wave to input port. Displacement of the SAW through the thickness of piezoelectric substrate is recorded and proofed that SAW doesn't penetrate more than the designed thickness. Displacement along wave direction is also monitored.
