摘要： A frequency conversion unit comprising a local oscillator, first and second mixers, a first hybrid circuit and a second hybrid circuit, the mixers receiving, via the first hybrid circuit, local oscillation outputs from the local oscillator, and the second hybrid circuit receiving outputs from the first and second mixers, thereby producing a frequency conversion output signal therefrom. Intermediate frequency signals used in the first and second mixers are n radian out of phase with each other. The first hybrid circuit produces outputs for the first and second mixers having a predetermined phase difference of φ 1 therebetween . The second hybrid circuit receives outputs from the first and second mixers and combine them after making a phase difference of (x - φ 1 ) therebetween.

摘要： The invention relates to a dielectric filter with attenuation poles. A first dielectric block or blocks (1) have a cut out portion and the cut out space is filled with a second dielectric block (6). A bypass pattern (7) is formed on the second dielectric block (6) and is capacitively coupled with two resonance elements formed on the first dielectric blocks (1). The dielectric filter is compact, and the position and intensity of attenuation poles can be freely designed and easily adjusted.

摘要： A resonator element (5) formed of a half or a quarter of dielectric cylinder contacts an electrically conductive plane (11) via the resonator element's radially cut side (5′) which includes the axis of the cylinder, accordingly, resonates in TE 01δ -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 (5′) of the resonator element (5) through an opening provided on the electrically conductive plane (11). Coupling circuit according to the present invention allows a compact overall circuit configuration.
