摘要： A surface acoustic wave filter arrangement is described herein. The surface acoustic wave filter arrangement includes a first gate configured to operate symmetrically or asymmetrically, and a second gate configured to operate symmetrically. The filter arrangement also includes a double-mode surface acoustic wave (DMS) filter structure including an input connected to the first gate, and an output. The output includes a terminal pair that includes two symmetrical terminals configured to operate symmetrically. Each of the two symmetrical terminals of the terminal pair is electrically connected at the output of the DMS filter structure to a cascaded resonator.

摘要： An electric filter has a band-pass filter that includes a track with acoustically coupled electroacoustic transducers. The filter includes a band-stop filter with at least one electroacoustic series element and at least one electroacoustic parallel element. The series element of the band-stop filter is connected in series to at least one of the transducers of the band-pass filter. The parallel element of the band-stop filter is arranged in a shunt arm that is electrically connected to at least one of the transducers of the band-pass filter. In at least one of the electroacoustic elements of the band-stop filter, the resonance frequency and the anti-resonance frequency lie outside the passband of the band-pass filter.

摘要： A SAW filter circuit having improved ESD resistance is specified, in which a series interconnection composed of SAW resonators is interconnected between a first signal port and a DMS port. The static capacitance of the series interconnection is at most four times the static capacitance of the DMS transducers interconnected therewith.
