摘要： A coaxial resonator comprising an outer conductor with closed and open ends, an inner conductor concentrically disposed in the outer conductor to establish a short circuit at the closed end and an open circuit at the open end, and a dielectric member mounted in the open circuit between the outer and inner conductors. An electrode is connected to the open circuit end of the inner conductor with a spacing from the dielectric member. A conductive plate, having a smaller surface area than that of the electrode but larger than the transverse cross-sectional area of the inner conductor, is provided between the dielectric member and the electrode. The dimensions of the conductive plate is appropriately chosen to accommodate frequency variations which might occur as a result of a connection with an external circuit.

摘要： A coaxial type microwave filter having an outer conductor and at least one inner conductor supported in the outer conductor has a strip transmission line extending from an external strip-line circuit to the inner conductor through an opening in the outer conductor. The strip transmission line includes a dielectric member forming an integral part of the dielectric substrate of the external circuit and a thin layer of conductive strip also forming an integral part of the conductive film pattern of the external circuit. The extending strip transmission line is electromagnetically coupled with the inner connector to permit the two microwave circuits to be interconnected with no use of a connector.

摘要： A comb-line bandpass filter comprising an enclosure or outer conductor and a plurality of inner conductors arranged parallel in the outer conductor. Adjacent to one end of each inner conductor a body of dielectric material is attached to provide a larger diameter, lumped capacitance section while providing a lumped inductance section in the remainder of the inner conductor. A conductive layer, conductively coupled to the outer conductor, encircles the dielectric body to act as a shield between adjacent inner conductors so that the coupling between them is concentrated in the inductive section. Overall size of the comb-line filter is reduced by reduction both in axial length of the inner conductors and the spacing between them.

摘要： In a band stop filter having a plurality of series resonating circuits, and coaxial cables connected between the series resonating circuits, the length of each of the coaxial cables is made either shorter or longer than quarter wavelength at the center frequency. With this arrangement, asymmetry is introduced in the insertion loss vs frequency characteristic curve so that the curve is sharper than the symmetrical curve in a given range, resulting in a reduction of insertion loss at a transmission band which resides either above or below the center frequency. Two band stop filters may be combined to constitute an antenna coupler for connecting a transmitter and a receiver to a common antenna. Each of the series resonating circuits used in the band stop filter may be constructed of a quarter wavelength coaxial resonator, which functions as a parallel resonating circuit, and a loop-like coaxial cable, which functions as a coupling capacitor.

摘要： In a double superheterodyne tuner for receiving TV channel signals, a frequency in a range defined between 2520 and 2700 MHz is selected as the first intermediate frequency, while the first intermediate frequency is obtained by subtracting a desired channel frequency from a first local oscillator frequency. The tuner comprises first and second mixing circuits respectively used for effecting frequency conversion, where each of these mixing circuits has parallel coupled lines so that each mixing circuit operates as a balance-to-unbalance transformer. The second mixing circuit further comprises a short-circuit line placed between the parallel coupled lines. The tuner also comprises a band pass filter having a band width less than 5 MHz, which selectively transmits the first intermediate frequency signal from the first mixing circuit.
