Micro acoustic filter crosstalk is compensated, and a method to compensate the

摘要

Micro acoustic filter having a first and second converters is proposed, by the crosstalk electro-magnetic and capacitive properties, providing a current loop of the additional coupling capacitance added between the first and second converters is compensated. Current loop and coupling capacitance of the additional is disposed to act in the opposite direction in terms of positive and negative sign for the natural bond which is set by the design, to be able to fully compensate this by doing so at this time.
