  • Publication number: 20130154757
    Abstract: In a composite electronic module, electronic components including magnetic substances are mounted on a substrate such that lines of magnetic force generated by a permanent magnet of a non-reciprocal circuit element are concentrated to the non-reciprocal circuit element side. Therefore, even when a metal yoke is omitted, for example, it is possible to reduce the number of lines of magnetic force generated by the permanent magnet and which leak to the outside of the substrate, and hence to significantly reduce and prevent the influence of a magnetic field generated by the permanent magnet upon other electronic components that are arranged near or adjacent to the composite electronic module around the substrate.

  • Publication number: 20130154785
    Abstract: In a laminated inductor element, a magnetic ferrite layer sandwiched between two conductor patterns is thinner than other magnetic ferrite layers. Therefore, a crack occurs in the magnetic ferrite layer due to firing. As a result of the occurrence of this crack, a stress applied to each layer is relaxed, and it becomes possible to avoid warpage, a crack, or the like. In addition, in the laminated type inductor element, the two conductor patterns are electrically connected by two via holes, and subjected to a same potential. Since the two conductor patterns correspond to a same wiring pattern and a coil of coil conductor is defined by the two conductor patterns, even if upper and lower coil conductors are electrically in contact with each other due to the crack, the two conductor patterns are not put into a short-circuited state.

  • Publication number: 20130154768
    Abstract: A laminated balanced filter includes one unbalanced terminal, two balanced terminals, a ground terminal, an unbalanced-side LC parallel resonator, an intermediate LC parallel resonator, and a balanced-side inductor. The inductor electrode pattern of the balanced-side inductor includes a first portion extending from one end portion to a connection portion and a second portion extending from the other end portion to the connection portion. A direction of a current flowing through the first portion is opposite to a direction of a current flowing through the inductor electrode pattern of the intermediate LC parallel resonator. A direction of a current flowing through the second portion of the balanced-side inductor is the same as a direction of a current flowing through the inductor electrode pattern of the intermediate LC parallel resonator. The laminated balanced filter further includes a coupling capacitor connected between a balanced terminal connected to the first portion and an unbalanced terminal.

  • Publication number: 20130147674
    Abstract: Radiation electrodes are formed on a dielectric base body of an antenna chip. A capacitive feeding electrode is formed on a first end surface of the dielectric base body. A ground electrode, a feeding circuit connection electrode, feeding lines, a tip electrode, and the like are formed on the top surface of a base member of a substrate. When a first switching element selects the feeding line side, a second switching element is made to enter a conducting state. In this state, the radiation electrodes are capacitively fed. When the first switching element selects the feeding line side, the second switching element is made to enter an open state. In this state, the radiation electrodes are directly fed. In this manner, the directivity direction of an antenna can be switched using a single radiation element.
