摘要： A dielectric filter and a dielectric duplexer adapted to two frequency bands formed by using a single component are disclose, in addition to a communication apparatus using the same. In this case, since a dielectric block used as the single component can be easily molded and grasped, production efficiency can be enhanced. The dielectric duplexer adaptable to two frequency bands is formed by disposing inner-conductor-formed holes acting as &lgr;/2 resonators and &lgr;/4 resonators in the single dielectric block.

A pair of an input electrode and an output electrode which are not brought into electrical contact with the outer conductor and are independent of each other is provided in a position in proximity to the opened end face on the outer peripheral surface of the dielectric block, and respective portions of both the electrodes are extended to the side surfaces, which are respectively adjacent to the electrodes, of the dielectric block. Consequently, the input electrode and the output electrode are capacitively coupled to each other, and the input electrode and the output electrode are respectively capacitively coupled to the inner conductor. Coupling capacitance can be adjusted by the areas of the electrodes.

摘要： A shield that can prevent the thickness of a dielectric filter from increasing without increasing the manufacturing cost of the dielectric filter is disclosed. The shield of the present invention is to be attached to a dielectric filter and has a first plate, a second plate elongated from the first end of the first plate in a predetermined direction, a third plate elongated from the second end of the first plate opposite to the first end in the predetermined direction, and a projecting part projecting from the first plate at a portion between the first and second ends of the first plate. Since the shield can be fixed to the dielectric filter by pinching the both side of the dielectric block and the projecting part can be in contact with the metallization of the dielectric filter, the total thickness of the dielectric filter does not increase even the shield is attached.

摘要： 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.
