摘要： A high-frequency switch having two input terminals and two output terminals of which a broad pass band is required has (i) a circuit board that has two input electrodes along one side and two output electrodes along another side, and (ii) four PIN diodes mounted on this circuit board. Each side of the quadrangle made by connecting the input electrodes and the output electrodes is not parallel to the corresponding side of the quadrangle made by connecting electrodes for mounting the PIN diodes. Each side and the corresponding side form an angle other than 180°. This structure can provide a high-frequency switch capable of reducing a transmission loss in the paths and facilitating impedance matching.

摘要： A laminated high frequency device includes a laminated body including plural magnetic sheets having relative permeabilities larger than 1, inductor patterns for forming plural inductors in the laminated body, and capacitor patterns forming a capacitor. The capacitor patterns are opposed to each other about another sheet of the laminated body. The inductors have large inductances without thickening of the magnetic sheet or thinning of the inductor patterns providing a large conductor loss. This arrangement reduces a size of the laminated high frequency device while providing isolation between the inductors.

摘要： The present invention relates to an antenna mainly used in a cellular phone or the like and to a communication terminal using it. It is hence an object thereof to realize an antenna having a high radiation efficiency, a wide adjustable range of the impedance of the antenna, and a capability of matching with an RF circuit by the structure itself without using a matching circuit. The number of structural parameters for adjusting the impedance of the antenna increases. To achieve the object, the antenna in the communication terminal of the present invention has a radiation element wound spirally around an insulating core in the winding direction inverted at an arbitrary position. The antenna is hence capable of adjusting the impedance, and as a result, the number of structural parameters of the antenna increases, and the adjustable range of the impedance of the antenna is expanded.
