摘要： The present invention relates to a surface acoustic wave (SAW) filter which is used for cellular phones and other mobile communication equipment. The object of the present invention is to realize a SAW filter of which attenuation characteristics and pass characteristics can be set arbitrarily. The SAW filter of the present invention comprises comb-shaped electrodes facing each other disposed on the same piezoelectric substrate, at least two resonators with an input and output terminals, and an equivalent transmission line which is connected between an output terminal of a first resonator and an input terminal of a second resonator. The phase of the transmission line can be adjusted from 5 degrees to 175 degrees arbitrarily at the series resonance frequency of the resonators. This structure realizes a band-stop filter or a band-pass filter whose attenuation characteristics and pass characteristics can be set arbitrarily.

摘要： The invention relates to a SAW filter, an antenna duplexer using the same, and a mobile communication terminal using the same, and assures a high withstanding power characteristic and a sufficient isolation between transmitting terminal and receiving terminal. The invention relates to a ladder-type SAW filter composed by alternately connecting a serial branch having at least one SAW resonator connected in series to a signal path, and a parallel branch having at least one SAW resonator connected between the signal path and the ground, in which the sizes of wiring patterns of the parallel branch are smaller than wiring patterns of the serial branch. Therefore, in the case of the serial-branch input type, inductive components of the parallel-branch wiring patterns can be decreased, so that a large reflection coefficient may be obtained in the rejection band.

摘要： A band switching filter includes a resonator circuit having a surface acoustic wave resonator, a switching element and an impedance element. The filter selectively passes or attenuates a signal through one of two pass bands using a single filter. The resonant frequency of the resonator circuit can be shifted to another frequency by selectively connecting the surface acoustic wave resonator to an impedance element using a switching element.
