    • A duplexer comprising a transmit resonator device and a receive resonator device for filtering transmit and receive signals. The resonator device has a first BAW resonator for generating an acoustic wave signal from an input electric signal, a first acoustic delay for delaying the acoustic wave signal, and an intermediate BAW resonator for receiving the delayed acoustic wave signal at one end and converting the delayed acoustic wave signal to an electric signal. Through electrical coupling, the electric signal also appears at another end of the intermediate BAW resonator for generating a further acoustic wave signal at the other end. The resonator further comprises a second delay for delaying the further acoustic wave signal, and a second BAW resonator for producing an output electric signal from the delayed further acoustic wave signal. The duplexer can be used in a transceiver in a mobile phone.

    • A rotation sensor has a substrate (112) with a first surface (114) and a second surface (116). A shear-wave transparent mirror (106) is arranged on the first surface (114) of the substrate (112), and a shear-wave isolator (104) is arranged above the shear-wave transparent mirror (106), the shear-wave transparent mirror (106) and the shear-wave isolator (104) being arranged separated from each other to define a Coriolis zone (124) there between. A bulk-acoustic-wave resonator (102) is arranged above the shear-wave isolator (104), and a shear-wave detector (108) is arranged on the substrate (112) in a direction, in which a shear-wave (128) generated by the bulk-acoustic-wave resonator (102) upon rotation propagates.
