Abstract :
An equivalent circuit with parasitics is described to predict stop band frequency response of flip-chip surface acoustic wave (SAW) filters, 3.2×2.5 mm2 and 2.5×2.0 mm2 in size. An input to output coupling capacitance and a common ground inductor provide a distinct trap response in the stop band. In order to improve the stop band response of the filter, a design technique utilizing parasitics is proposed
