摘要： The invention relates to an arrangement comprising a DMS filter, in which at least one transducer (W) of the DMS filter (DMS) is sub-divided into two electrically parallel-connected sub-transducers (T,T') which are moved apart in relation to one another by an amount of at least half a wavelength. This leads to the signals of the two sub-transducers being mutually triggered at a frequency in a stop band, thus creating an attenuation pole in the upper attenuation band.

摘要： The filter comprises at least one acoustic track formed on a piezoelectric substrate. At least one SAW input transducer and at least one SAW output transducer are arranged in each track. Each track has a RSPUDT structure and thus a distributed excitation. The excitation function comprises sources arranged in a main lobe and a tail function comprising at least one tail lobe. A fine and precise approximation to the desired continuous excitation function is obtained by decreasing the excitation strength in the tail function by a factor of at least 2.
The excitation strength may be varied by connecting tail-lobe sub-transducers of a first track and a second track in series or in parallel. A capacitor may be circuited in series between main lobe and tail lobe sub-transducers.

摘要： In order to provide a SAW filter having a wide passband matching to the digital TV broadcast waves so as to be low-loss, and obtaining a sharp and large attenuation in the outside of the TV broadcast waves, a constant-K filter is composed of series arm SAW resonators (11,15) and parallel arm SAW resonators (12,16), and a circuit component is formed by connecting an inductor (14,21,22) for shifting a resonant point/antiresonant point to the series arm SAW resonator in series or to the parallel arm SAW resonator in parallel. A plurality of the circuit components are connected in a cascade connection to each other in a plurality of stages via inductors (19) for shifting the resonant point/antiresonant point.

摘要： The present invention relates to a surface acoustic wave filter for use in a mobile communication device such as a portable telephone. As for the surface acoustic wave filter provided with a plurality of serially connected surface acoustic wave resonators, the invention aims at realizing the filter that is simple to design. The invention comprises a grounding electrode 12, serially connected surface acoustic wave resonators 15a through 15c, coupling electrodes 16a through 16d for the resonators, and inter-digital electrodes 20a through 20d formed from the coupling electrodes 16a through 16d, all formed on a surface of a piezoelectric substrate 11. The surface acoustic wave resonators 15a through 15c and capacitances 19a through 19d can be designed independently with respect to each other, as the capacitances 19a through 19d are formed by the inter-digital electrodes 20a through 20d and the grounding electrode 12.

摘要： A surface acoustic wave resonator is constituted by an IDT electrode and reflector electrodes disposed on both sides thereof, on a piezoelectric substrate. Two of said surface acoustic wave resonators are disposed nearby so that the propagation directions of the respective surface acoustic waves are in parallel to each other to make acoustic couple to constitute a surface acoustic wave filter having plural exciting modes with different propagation frequencies. The bus bar electrodes of each of two IDT electrodes are electrically separated from each other, and the leading out electrodes led out from at least two spots on those bus bar electrodes are electrically connected to each other, by which one side of the balanced input and output terminal. As a result, the electrode resistance of the IDT electrode is alleviated to make the insertion loss less.
