Abstract

In the present paper, a 70 MHz LiNbO3 SAW filter device is designed, modelled and simulated. The frequency sampling methods and the windowing methods are adopted, and using user defined MATLAB® simulation tool was employed for developing the algorithms. A computationally simulated frequency response of 70 MHz SAW filters has compared with experimental device result. These device responses utilized and implemented during the design and development stage of these devices for their potential applications in mobile communication systems (GSM/CDMA/WCDMA) for filtering the higher order as well as intermediate frequencies.
