    Abstract: PROBLEM TO BE SOLVED: To provide additional circuity for suppressing an insertion loss of a signal path, preventing electrostatic discharge and securing robustness. SOLUTION: A duplexer for connection with an antenna comprises an antenna port, a transmitting filter comprising bulk acoustic wave (BAW) resonators having a first antenna side impedance coupled with the antenna port, a receiving filter comprising BAW resonators having a second antenna side impedance coupled with the antenna port, and a shunt inductance coupled between the antenna port and ground. The shunt inductance and the first and second antenna side impedances of the transmitting filter and the receiving filter are selected in such a way that the shunt inductance turns the first and second input impedances in a negative direction in a Smith diagram.

    Abstract: PROBLEM TO BE SOLVED: To provide a BAW (bulk acoustic wave) resonator which has a plurality of layers to increase the function of the resonator.
    SOLUTION: The BAW resonator includes a piezoelectric layer 102, a first electrode 104 on a front surface, a second electrode 106 on the opposite surface, a substrate 108, and an acoustic reflector 110 provided between the substrate 108 and the second electrode 106. The acoustic reflector 110 has a plurality of alternately-arranged layers made of a material having a high acoustic impedance and made of a material having a low acoustic impedance. The function of the acoustic reflector 110 is determined by the reflectivity of longitudinal wave and the reflectivity of traverse wave which exist in the BAW resonator 100 with a resonant frequency of the BAW resonator 100. The acoustic reflector 110 and layers 106a and 106b provided between the acoustic reflector 110 and the piezoelectric layer 102 are chosen so that transmittance of the longitudinal wave and transmittance of the traverse wave at the resonant frequencyare less than -10dB, referring to the number of these layers, the material and thickness thereof.

    Abstract: A bulk acoustic wave device having two resonators in a stacked-up configuration separated by a dielectric layer. The device can be coupled to a lattice filter or a ladder filter to form a passband filter with an unbalanced input port and two balanced output ports. One or more such passband filters can be used, together with another lattice or ladder filter, to form a duplexer having an unbalanced antenna port, two balanced ports for one tranceiver part and two balanced ports for another tranceiver part.

    Abstract: The invention relates to a video projection system that is provided with a laser that emits a laser beam. The laser beam is deflected onto the projection surface by means of a deflection unit. The projection surface contains luminous substances which generate light beams when the laser beam impinges, whereby said light beams have a predetermined wavelength. The light beams generated by the luminous substances are detected using a detection unit. The intensity of the laser beam is controlled according to desired video data and the detected light beams and by means of a control unit.
