| Abstract | ||||
| This paper proposes a design of a bandpass filter based on the wavelet transform (WT) technique using a surface acoustic wave device (SAW). The proposed model is achieved through the impulse response model from the equivalent circuit of mason (ECM). This paper aimed to study the behaviour of a bandpass filter with a center frequency of 70MHz suitable for intermediate frequency (IF) stages of mobile phones and various communication systems. The study includes different piezoelectric materials such as ST quartz, Lithium niobate (LiNbO3) and Lithium tantalate (LiTaO3). Moreover, the transfer function, bandpass ripples, sidelobes power and insertion loss for input and output Inter-digital transducers are evaluated and simulated. The calculated parameters include the size of the substrate processing time and the scale of the wavelet function. The simulated results are compared with uniform aperture surface acoustic wave devices. The designed substrate dimensions of 2mm×2mm and sidelobes attenuation is up to 96.61 dB. | ||||
