A filter including a piezoelectric substrate; a surface acoustic wave (SAW) device on the piezoelectric substrate and including unequally spaced interdigitated input and output transducer electrodes of unequal widths, wherein the input transducer electrodes are to convert an incoming radio frequency (RF) electrical signal into surface acoustic waves; a SAW propagation path between the input and output transducer electrodes; and a magnetostrictive film in the SAW propagation path to filter the surface acoustic waves that are at a ferromagnetic resonance frequency of the magnetostrictive film, wherein the output transducer electrodes are to convert the filtered surface acoustic waves into an outgoing electrical RF signal. The SAW device may operate in a wide-band pass configuration. The wide-band pass configuration result in a transmission of frequencies up to &#x2212;60 dB. The magnetostrictive film may include a ferromagnetic material. The interdigitated input and output transducer electrodes may include unequal widths between adjacent electrodes.
