    摘要: An antenna duplexer has a transmission input terminal, a receiving output terminal, an antenna terminal in which a transmission output terminal and a receiving input terminal are used in common, a transmission filter having at least one resonance element set between the transmission input terminal and the transmission output terminal and coupled by a coupling element, a receiving filter having at least one resonance element set between the receiving output terminal and said receiving input terminal and coupled by a coupling element, and an impedance variable element connected to the resonance element of the transmission filter and the resonance element of said receiving filter respectively in parallel, wherein the frequency transfer characteristic of the transmission filter and the frequency transfer characteristic of the receiving filter are controlled by applying control signals and thereby changing the impedances of the impedance variable element.

    摘要: The disclosure is directed to a coaxial resonator such as a λ/4 coaxial resonator (5) or the like to be used for an electrical filter or oscillator, etc. which operates, for example, in UHF ranges. The coaxial resonator includes a stator electrode (8a, 8b) provided on the resonator main body (6), a rotor of a dielectric material (10) formed with a rotor electrode (9) confronting the stator electrode and rotatably mounted on the resonator main body so as to vary capacity between the stator electrode and the rotor electrode through rotation of the rotor for alterations of the resonance frequency.

    摘要: A notch filter is made up from laminated dielectric, which attenuates a specific frequency of a signal to be transmitted, and comprises two terminals (1) for input and output of a signal to be transmitted, a line (4) connected between those terminals (1), two resonators (3) each having one end connected to ground and an other end, two first coupling capacitors (2), and a second coupling capacitor (5). Ends of the line (4) are connected to the other ends of the resonators (3) through the first capacitors (2). The second capacitor (5) couples said two resonators (3) to one another.
