摘要： A band-pass filter includes electrodes formed on both upper and lower surfaces of a dielectric plate, and a plurality of non-electrode portions on the upper and lower surfaces of the dielectric plate so that the non-electrode portions face each other across the dielectric plate to form resonators in regions confined by the non-electrode portions on the dielectric plate. The resonators other than at least input- and output-stage resonators are n&lgr;2 resonators, where &lgr; denotes one wavelength and n is an integer more than one. The first- and second-stage resonators, and the third- and fourth-stage resonators are magnetically (inductively) coupled, and the second- and third-stage resonators are capacitively or inductively coupled. The band-pass filter therefore provides satisfactory attenuation characteristic from the pass band to the stop band, and can also be compact and lightweight.

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 nonradiative dielectric waveguide filter of the present invention permits the manufacturing process including the production of a dielectric strip to be simpler. The filter can be formed by a pillar dielectric strip. The nonradiative dielectric waveguide filter includes resonators, input-output connection units, and cut-off regions, in which the upper and lower conductor plates and a dielectric strip disposed therebetween form the filter. In one example, the main signal-transmitting mode is the LSM mode; a groove having a bottom and conductor walls is disposed in a position in which the conductor plates are opposing; the resonator is formed by fitting the dielectric strip into the groove; and the cut-off regions are formed by second grooves formed in the conductor plates adjacent to the dielectric strip.

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.
