摘要： A resonator element formed of a half or a quarter of dielectric cylinder contacts an electrically conductive plane via the resonator element's radially cut side which includes the axis of the cylinder, accordingly, resonates in TE.sub.01.delta. -mode. On an opposite side of the electrically conductive plane there is provided an unbalanced transmission line, for example, of a strip line type or a coaxial line type. An end of the transmission line is electromagnetically coupled via a dielectric material in the transmission line or directly with the radially cut side of the resonator element through an opening provided on the electrically conductive plane. Coupling circuit according to the present invention allows a compact overall circuit configuration.

摘要： A frequency conversion unit comprising a local oscillator, first and second mixers, first and second hybrid circuits. The mixers receive, via the first hybrid circuit, local oscillation outputs from the local oscillator, and the second hybrid circuit receives outputs from the first and second mixers, producing a frequency conversion output signal therefrom. Intermediate frequency signals used in the first and second mixers are .pi. radians out of phase with each other. The first hybrid circuit produces outputs for the first and second mixers having a predetermined phase difference of .phi..sub.1 therebetween. The second hybrid circuit receives outputs from the first and second mixers and combines them after making a phase difference of (.pi.-.phi..sub.1) therebetween.

摘要： A high-frequency circuit apparatus includes two high-frequency circuits (2, 3) mounted on a printed circuit board (1), two rows of first plated through holes (6) which connect upper and lower ground plates (4, 5) on the upper and lower surfaces of the printed circuit board (1) and which are arrayed in a first direction so that the two high-frequency circuits (2, 3) are disposed between the first plated through holes, and at least two columns of second plated through holes (7) which are arrayed in a second direction different from the first direction, between the two high-frequency circuits to connect the ground plates on the upper and lower surfaces of the printed circuit board, to thereby form a waveguide resonator. A variable capacitance diode can be provided to be connected to a conductor pattern which is electrically isolated from the ground plates and the ground plates so as to adjust the resonance frequency of the waveguide resonator.

摘要： In order to improve filter loss of a waveguide filter having coaxial/waveguide mode conversion parts at its ends, conductor posts bridging a space between two long sides of the waveguide are provided between the parts and the ends. The conductor posts have sufficient thickness and remain close enough to each other and to short ends of the waveguide that a partition plane including axes of the conductor posts can be regarded as an imaginary short plane. The conductor posts are located so that the partition plane is positioned at a distance .lambda./4.times.n (n=1, 3, 5 . . . ) from the coaxial/waveguide mode conversion part.
