Abstract
Disclosed is a high-frequency band pass filter of simple structure for use in a frequency range from hundreds of MHz to over ten GHz. The band pass filter comprises a magnetic loss sheetprepared by dispersing fine powder of averaged particle size up to 30 μm of a soft magnetic metal such as an Fe—Cr—Al alloy, an input signal lineand an output signal linemade of a conductive strip disposed in serial direction with a gap between them, a capacitance means connecting the opposite ends of the lines and a GND linedisposed on the reverse side of the sheet. The capacitance means may be either a chip condenser, or that formed by disposing an internal lineof another conductive strip with intermediation of insulating filmto bridge on the input signal lineand the output signal lineto have overlapping parts.
