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.

This antenna duplexer includes two surface acoustic wave (SAW) filters for transmission and reception having passing bands of mutually different frequencies, a phase shift substrate, and a package for accommodating them. The passing band of each antenna duplexer is mutually different from other's passing band. This multi-frequency antenna duplexer includes a plurality of antenna duplexers. In one package, transmitter surface acoustic wave filters, receiver surface acoustic filters, and phase shift substrates are mounted. Thus, the multi-frequency antenna duplexer are reduced in size.

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 piezoelectric device includes a piezoelectric plate provided with at least one electrode at almost a central portion of each face; a first plate made of an ionic material having a recessed portion to cover the at least one electrode at one face to face the piezoelectric plate; and a second plate made of an ionic material having a recessed portion to cover the at least one electrode at one face to face the piezoelectric plate. Each of the at least one electrode is packaged by direct bonding the piezoelectric plate with the first plate and the second plate so as to be sandwiched therebetween. A package includes a body member made of an ionic material provided with a recessed portion or an opening, having a flat face around the recessed portion or the opening; and a covering member made of an ionic material having a flat face to cover the body member. The flat face of the body member and the flat face of the covering member are cleaned and attached to each other so as to be direct bonded with each other using hydrogen bonds generated between the ionic materials, thereby packaging the recessed portion or the opening.
