RF Filtering & Wavelet Transforms
This research introduces a novel surface acoustic wave (SAW) bandpass filter architecture centered at 1747.5 MHz, integrating wavelet transform principles into its design and analysis. Unlike traditional Fourier-based methods, wavelet transforms offer localized time-frequency resolution, facilitating more efficient decomposition of transient signals and improved handling of non-stationary components. This integration enhances control over filter characteristics, leading to superior passband sharpness, side-lobe attenuation, and spectral confinement. The filter design uses a multi-stage configuration, augmented by various window functions like Gaussian, Kaiser, Hanning, and Hamming, to achieve precise null bandwidth control and effective side-lobe suppression. Finite element modeling (FEM) with COMSOL Multiphysics and wavelet-domain signal processing with MATLAB were used to validate the electromechanical behavior and spectral performance.
