摘要： A high-frequency circuit device includes a substrate and a high-frequency circuit. The high-frequency circuit is provided on the substrate and has a signal line. The signal line is configured with a slot line provided by electrodes that are arranged side-by-side with a space therebetween on the substrate. The slot line can facilitates circuit design compared to a microstrip line and has significantly low conduction loss compared to a coplanar line, and can improve the Q-value of the high frequency circuit. This can provide an improved high-frequency circuit device having small phase noise. The high-frequency circuit device, which also serves as an oscillator, employs a slot output and thus can provide an advantage of better continuity for a class-B push-pull amplifier that operates more efficiently than a class-A one.

摘要： A radio-frequency amplifier comprises slot lines formed in a top electrode which are bent to define matching segments that are perpendicular to transmitting segments. The matching segments have a length corresponding to one-quarter of the wavelength of a signal to be amplified and are at least partially perpendicular to the transmitting segments. A DC-cut circuit comprising slot lines is connected to the matching segments, an FET is connected to the transmitting segments and the matching segments, and respective matching circuits serve as an input unit and an output unit of the FET. Source terminals of the FET are connected to parts of a top electrode that do not lie between the segments. A drain terminal and a gate terminal are connected, to be electrically separated from each other, to parts of the top electrode, which are electrically separated from the source terminals by the DC-cut circuit, the transmitting segments, and the matching segments.

摘要： A radio frequency module includes a multi-chip substrate divided into separate substrates. An antenna block, a duplexer block, a transmitter block, a receiver block, and an oscillator block are formed on the separate substrates. Connection resonators, which are connected to transmission lines, are formed at edges of the separate substrates. The connection resonators on adjacent ones of the separate substrates are arranged close to each other such that the two adjacent resonators are electromagnetically coupled to each other. Thus, the transmission lines on the separate substrates are interconnected, and a signal can be propagated among the blocks.

摘要： A planar circuit having a conductive film on either main surface of a substrate. The conductive film on one of the main surfaces is patterned with two-dimensionally and repeatedly arranged unit cells, which are basic conductor patterns. Each of the unit cells has a capacitive region at the center thereof. Capacitance is induced between the center area and the conductor film formed on the main surface of the substrate opposite the center area. An area located near the middle of each of sides in the peripheral portion serves as an inductive region. In any two adjacent unit cells, the inductive regions have a multiple spiral-shaped conductor pattern, in which the center ends thereof are connected to each other at a halfway position between the two unit cells, and the outer peripheral ends thereof are connected to the capacitive regions.

摘要： The invention provides. a dielectric resonator for example in the TE010 mode characterized in that electrodes are formed on both principal surfaces of a dielectric plate in such a manner that influence of spurious waves propagating in a space between the electrodes and a conductive plate is prevented thus preventing the reduction in Qo and degradation in the attenuation characteristic in the frequency ranges outside the passband. The inner diameter of the cavity is selected such that when the cavity is regarded as a waveguide the cutoff frequency of the waveguide becomes higher than the resonant frequency of a resonance region and such that the inner diameter of the cavity is greater than a non-electrode part.
