摘要： A stripline filter includes a cylindrical substrate made of a dielectric material and having inner and outer surfaces with opposite ends thereof opened. A ground electrode is deposited on the inner surface, and on the inner surface, interdigitated electrodes are deposited. Alternately, the ground electrode may be deposited on the outer surface, and the interdigitated electrodes may be deposited on the inner surface. Thus, the stripline filter can be arranged in a compact size. Also, the ground electrode provided on the outer surface prevents electromagnetic waves generated from the interdigitated electrodes from being emitted out.

摘要： The present invention provides a solution to a problem that a composition including a reactive silicon group-containing polyether undergoes red coloration. More specifically, in a reactive silicon group-containing organic polymer which contains Co, the problem concerned is solved by limiting the Co content to 0.5 ppm or less. As the reactive silicon group-containing organic polymer, for example, a reactive silicon group-containing polyether (A) or a mixture of the reactive silicon group-containing polyether (A) and a vinyl polymer (B) may be cited. The reactive silicon group-containing polyether (A) is obtained, for example, by reacting a polyether or a derivative thereof which contains Co in a content of 0.5 ppm or less with a silane compound which has a group capable of reacting with the polyether or the derivative thereof and has a hydrolyzable group.

摘要： First and second transmission paths P1 and P2 are disposed between a first port #1 connected to an antenna ANT and a second port #2 connected to a transceiving circuit 10. The first transmission path P1 includes receiving filters Rx1, Rx2, and Rx2′, an amplification circuit LNA, and 90° hybrid circuits 12 and 14. The second transmission path P2 includes a transmitting filter Tx1. A received signal amplified by the amplification circuit LNA is transmitted to the port #2 via the 90° hybrid circuits 12 and 14, but is not transmitted to the second transmission path P2. A transmission signal is transmitted from the port #2 to the second transmission path P2. This prevents oscillation of the received signal due to positive feedback. A transceiving filter device that prevents degradation in the insertion loss, noise figure, and group delay characteristics in the transmission frequency band or the receiving frequency band and that prevents oscillation, and a communication apparatus using the transceiving filter device are provided.

The dielectric filter includes a cavity in which a conductive layer is formed, and a cross-shaped dielectric resonator disposed within the cavity, the dielectric resonator having at least three resonant modes, and coupling loops being coupled to the dielectric resonator. A coupling loop couples to a resonant mode at a first stage, among the resonant modes of the dielectric resonator, and also couples to resonant mode at a third stage in approximately negative-phase with respect to the first stage.
