    摘要: A SAW duplexer includes a first SAW filter having a passband with a relatively low frequency, and a second SAW filter having a passband with a relatively high frequency. The first and second SAW filters each have a ladder-shaped circuit configuration. A bridging inductor is connected in parallel to at least one serial arm resonator in the second SAW filter. The bridging inductor includes a coiled portion provided on a multilayer package substrate. The coiled portion is defined by connecting first to third wires provided on first to third layers by via-hole conductors. First, third, and fifth via-hole conductors that define a coil return wire portion are disposed inside the coiled portion.

    摘要: In order to not only obtain excellent sound quality in a long-time recording mode not less than five times a standard recording mode by preventing, without narrowing a track pitch of a high-fidelity head, the high-fidelity head from tracing the third sound track from a target sound track as well as excellent picture quality free from crosstalk from an adjoining video track of a target video track but enable special playback without using a field memory in a video tape recorder, one head pair in conventional double azimuth type four heads for the standard recording mode and a threefold recording mode is used for video recording in the long-time recording mode and a head pair having a head width smaller than a width of a recording track is used exclusively for video playback in the long-time recording mode.

A sealing member is disposed on the principal surface of the substrate to cover and seal off at least one of the reception elastic wave filter element and the transmission elastic wave filter element. The sealing member has different thicknesses between a reception-element-covering region, which faces the reception elastic wave filter element on the side opposite from the substrate with respect to the reception elastic wave filter element, and a transmission-element-covering region, which faces the transmission elastic wave filter element on the side opposite from the substrate with respect to the transmission elastic wave filter element.
