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 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： Electrodes are formed on both top and bottom surfaces of a dielectric plate and grounded coplanar lines, as transmission lines, are formed on the top surface of the dielectric plate. A plurality of micro-strip lines, each composed of high-impedance lines and low-impedance lines alternately connected in series, is arranged at a pitch shorter than the wavelength of a wave traveling along the grounded coplanar lines. A spurious mode propagation blocking circuit thus constructed prevents a spurious mode wave, such as a parallel-plate mode, from traveling.

摘要： A radio-frequency radiation source comprises electrodes containing opposing electrodeless parts formed on both sides of a dielectric plate in which the electrodeless parts are made to function as a dielectric resonator, a slit formed in the electrodeless part, and a switching element mounted over the slit. Further, a transmission line coupled to the dielectric resonator is provided. As constructed this way, the resonance frequency of the resonator is switched by turn-on and turn-off of the switching element. When the resonator resonates with the frequency of a signal propagated through the transmission line, the energy of the electromagnetic field is radiated to the outside through a slot.

摘要： Electrodes are formed on respective two main surfaces of a dielectric sheet wherein each electrode has an opening formed at a location corresponding to the location of the opening formed in the other electrode. The part defined by the openings serves as a dielectric resonator. Coupling lines are formed directly in the electrode opening. Transmission lines are formed on a circuit board. The coupling lines and the corresponding transmission lines are connected to each other via bonding wires. This structure makes it possible to minimize the external Q of a resonant circuit using the dielectric resonator. If an oscillator is produced using this resonant circuit, it is possible to achieve a large frequency modulation with and large output.

摘要： The present invention provides a line transition and a method for manufacturing the same. The line transition is constructed such that a planar circuit can be arranged in the direction parallel to the propagation direction of electromagnetic waves propagating through a solid waveguide, the coupling characteristics of the solid waveguide with the planar circuit formed on a dielectric substrate are not influenced by the assembly precision of the waveguide and the circuit, and the line transition characteristics are not affected by a variation in manufacturing the dielectric substrate. Notches are formed at the edges of the dielectric substrate in the vicinities of coupled-line pattern segments formed on a dielectric substrate. The notches are formed by punching through holes in a ceramic green sheet serving as a motherboard, firing the motherboard, and cutting the motherboard using dicing lines passing through the through holes.
