  • Patent number: 6970056
    Abstract: A filter assembly includes a transmission filter, a reception filter, a change-over switch, and phase circuits. The transmission filter has first and second ends electrically connected to a first antenna terminal and a transmission terminal, respectively. The reception filter has a first end electrically connected to a second antenna terminal via the change-over switch, and a second end electrically connected to a reception terminal. A main antenna is connected to the first antenna terminal, and a diversity antenna is connected to the second antenna terminal. The change-over switch performs switching control to connect the reception filter to one of the first and second antenna terminals. Thus, the filters utilize a fixed number of resonators regardless of switching control of the change-over switch, thereby achieving optimum filter characteristics.

  • Patent number: 6909339
    Abstract: An excitation hole is provided inside a dielectric block and, on the outer surface of the dielectric block, an input-output terminal electrically connected to an inner conductor inside the excitation hole is formed at one end portion of the excitation hole. A grounding-electrode-free portion is provided on the surface opposite to an input-output electrode of a mounting substrate with which the input-output terminal makes contact. Thus, the electric field strengths in upward and downward directions toward an outer conductor of the dielectric block from the excitation hole are balanced to suppress spurious TE-mode signals, etc.

  • Patent number: 6667730
    Abstract: A display has a display panel of a first aspect ratio and is able to display on the display panel an image of a second aspect ratio whose width element is larger than that of the first aspect ratio. The display has a gate driver, a data driver, and a timing controller. The gate driver sequentially selects gate lines of the display panel. The data driver stores data for one gate line and supplies the data to one of the gate lines selected by the gate driver. The timing controller supplies control signals to the gate and data drivers so that predetermined data is displayed in top and bottom non-image areas of the display panel during a vertical blanking period. The display is capable of displaying images of different sizes.

    Abstract: A dielectric filter which has suitable attenuation characteristics and which readily exhibits desired characteristics. First, second and third inner-conductor holes having an inner conductor on each of the surfaces thereof are formed inside a dielectric block having an outer conductor on the outer surface thereof. First and second I/O electrodes extend from opposing side-surfaces to the undersurface of the dielectric block and are separated from the outer conductor. The side-surfaces are orthogonal to the direction in which the inner-conductor holes are arrayed in the dielectric block, and the undersurface is a mounting surface for facing a mounting board. The first I/O electrode extends from one of said side-surfaces near the first inner-conductor hole, to a position beyond a remote side of the second inner-conductor hole, that is, the side near the third inner-conductor hole.

  • Patent number: 6590475
    Abstract: A filter with which it is possible to control the relationship between a pass band and an attenuation band. In this filter, for example, a single-stage trap filter is electrically connected to a three-stage band pass filter via a coupling capacitor. The trap filter has a serial resonance section composed of a resonator and a resonance capacitor. The serial resonance section is connected in parallel to a capacitive reactance element (capacitor), and a serial circuit composed of an inductive reactance element (inductor) and a PIN diode as a switching element. The capacitive reactance element and the inductive reactance element both serve to make an admittance of the trap circuit substantially zero.
