Differential saw filter including series coupled resonant/antiresonant tracks

Differential saw filter including series coupled resonant/antiresonant tracks

Resonant and anti-resonant inter digital transducers are coupled on acoustic tracks (302, 304, 306) of a piezoelectric substrate (301) to provide a balanced differential surface acoustic wave (SAW) filter (300).
