Abstract: PROBLEM TO BE SOLVED: To miniaturize an antenna branching filter when housing two branching filters in a single package. SOLUTION: The antenna branching filter has at least two pairs of branching filters, each of which consists of a surface acoustic wave filter for transmission and reception having different center frequencies and has an antenna pad, a transmission pad and a reception pad, a first and a second antenna terminals respectively connected to the first and the second antenna pads of the two pairs of filters, a first and a second transmission terminals respectively connected to the first and the second transmission pads of the two pairs of filters, a first and a second reception terminals respectively connected to the first and the second reception pads of the two pairs of filters, and a package for housing the two pairs of filters and having a rear surface consisting of a first to a fourth sides. The first and the second transmission terminals are formed on a first side and on a second side which do not face the first side respectively, the first and the second reception terminals are formed on the second side and a third side adjacent to the second side respectively, and the first and the second antenna terminals are formed on the fourth side.

Abstract: A resonator includes a piezoelectric thin-film provided on a main surface of a substrate, a first electrode film provided on a first surface of the piezoelectric thin-film, a second electrode film provided on a second surface of the piezoelectric thin-film, a frequency adjustment film provided on one of the first and second electrode films, the frequency adjustment film comprising a film laminate including a first adjustment film provided on said one of the first and second electrode films, and a second adjustment film provided on the first adjustment film. The first adjustment film is used for Deltaf adjustment, and the second adjustment film is used for correcting frequency deviations generated in the filter manufacturing process. Thus, it is possible to accurately control the center frequency of the filter in which the multiple resonators are connected.

Abstract: A piezoelectric thin-film resonator includes a film laminate formed on a device substrate (41), the film laminate including a lower electrode (43), a piezoelectric film (44) provided on the device substrate and the lower electrode, and an upper electrode (45) provided on the piezoelectric film. At least one of the upper and lower electrodes has an electrode leading portion that extends from an membrane in which the upper electrode overlaps with the lower electrode through the piezoelectric film and has a width narrower than that of the membrane.
