Acoustic, galvanic separating member comprising a single isolated, decoupled, stacked, acoustic volume resonator with acoustically resonant, electrical insulator comprises

摘要

Exemplary embodiments of the acoustic, galvanic separating means have a carrier signal source, a modulator, which is connected, in order to receive information signal and the carrier signal, a demodulator and an electrically separating, acoustic coupler between the modulator and the demodulator is connected. The acoustic coupler has at most a decoupled, stacked, acoustic volume resonator (idsbar = insulated decoupled stacked bulk acoustic resonators) on. An electrically separating, acoustic coupler, which is based on a single idsbar, is physically small and is inexpensive to manufacture, however, to conduct of information signals with data rates of more than 100 mbit / s in the position and has a considerable breakdown voltage between the inputs of the same and the outputs of the same on.
