Filter operating with surface acoustic waves.

摘要

The filter has at least one resonator (1, 2, 3) provided by an interdigitated transducer (1) and reflectors (2, 3) with a parallel resistance connected across at least one of the filter components, to provide protection against an electrostatic discharge by contact with electrostatically charged particles. The resistance is integrated in one or both reflectors of the resonator provided by 2 or more meanders (4, 5) which are connected in parallel with one another by transverse cross connections (6).
