    摘要： An antenna switching apparatus for selectively connecting an antenna to either a transmitter for transmitting a transmitting signal having a transmitting frequency, or a receiver for receiving a receiving signal having a receiving frequency, which is different from the transmitting frequency, includes an antenna terminal electrically connected to the antenna; a transmitting terminal electrically connected to the transmitter, and a receiving terminal electrically connected to the receiver. A receiving filter for passing a receiving signal therethrough is electrically connected between the antenna terminal and the receiving terminal. An impedance adjusting element is electrically connected to an input end of the receiving filter, and has an element value such that an impedance when seen from the antenna terminal looking toward the receiving filter becomes substantially infinity at the transmitting frequency. Further, a switching device is electrically connected between the antenna terminal and the transmitting terminal, wherein it is turned on or off in response to a control signal.

    摘要： The present invention relates to a balanced dielectric filter used in high-frequency circuits, such as those used for radio apparatuses, and provides a balanced dielectric filter having balanced input/output terminals. Namely, the balanced dielectric filter comprises two resonators, each comprising plural strip-line resonating elements, disposed in parallel and mutually coupled electro-magnetically, and input and output terminals coupled to each resonator so as to function as a pair of balanced input terminals and a pair of balanced output terminals, wherein the two resonators are located in a ceramic dielectric to face each other and to be mirror images of each other. The resonating element is a quarter-wavelength resonating element, the end of the strip line thereof is grounded. The strip lines and coupling electrodes are arranged among ceramic layers, whereby the filter is integrated into a ceramic-multilayered structure.

    摘要： In a laminated dielectric resonator, twomo strip line is formed and resonant frequency is lowered. Accordingly, the length of the resonator is reduced, and the length of the strip line becomes shorter than one fourth of the wavelength with the lowered resonant frequency, which leads to further reduction of the length of the resonator. By lowering the resonant frequency, dielectric material with less relative permittivity can be used, with a result of resonator with high unloaded Q and excellent temperature characteristic. Further, at least one coupling electrode is formed as external or internal electrode to compose a capacitor together with a second strip line, and a laminated dielectric resonator is connected to an external circuit via the coupling electrode. A dielectric filter such as band pass filter, band elimination filter is so composed that the dielectric resonators are cascade-connected to one another. In the thus constructed dielectric filter, external coupling capacitors are unnecessary, reducing the number of parts and facilitating the manufacturing process. Thus, a small-sized, low-cost dielectric filter is attained.
