Abstract: An impedance matching method which is used to save electrical energy by virtue of the fact that the method switches between modes for controlling impedance matching and modes for regulation of the impedance matching depending on the situation. An algorithm which, on the basis of control signals from an external circuit environment, controls or regulates the impedance of a variable-impedance circuit element is implemented in a logic circuit LC.

Abstract: A circuit is proposed by means of which a ceramic component having two electrodes can be provided with a uniform, but periodically alternating BIAS voltage. The component has properties dependent on the level of the BIAS voltage and, for the purpose of an increased service life, is connected to a generator for generating a BIAS voltage and to means for periodically reversing the polarity of the BIAS voltage present at the electrodes. In a method for operating the component having variable properties, a uniform BIAS voltage, the polarity of which is periodically reversed, however, is applied to the electrodes, and the service life of the component is thus increased.

Abstract: The invention relates to a bulk acoustic wave filter comprising at least one first resonator and at least one second resonator. A longitudinal acoustic mode for which normal dispersion is adjusted in the first resonator and abnormal dispersion is adjusted for the second resonator by selecting the material and the relative layer thicknesses, is able to propagate in the resonators, thus making it possible to improve especially the power compatibility of the filter at the higher frequency edge of the passband thereof.

Abstract: The invention relates to a duplexer with a transmit-receive path, which branches on the output side into a receive path and a transmit path. The receive path is preferably designed on the input side for transmitting an asymmetric signal and on the output side for transmitting a symmetric signal. A receive filter, which operates with surface acoustic waves, is arranged in the receive path. A transmit filter, which operates with bulk acoustic waves, is arranged in the transmit path. The filters are preferably constructed as separate chips, which are mounted on a common carrier substrate.
