<p><P>PROBLEM TO BE SOLVED: To obtain a high frequency absorption circuit which, without requiring special materials or manufacturing technology, can absorb a desired frequency component of a high frequency using general-purpose components and also exhibits a relatively large direct current or low frequency component current capacity. <P>SOLUTION: The high frequency absorption circuit comprises a first transmission line (5) having an electric length equal to approximately a half-wavelength of a target frequency to be absorbed, whose signal conductor (3) is connected at one end to a signal conductor of an input line (1) and connected at the other end to a signal conductor of an output line (2); a first resistive element (6) which is connected at one end to one end or near one end of the signal conductor of the first transmission line and connected at the other end to the other end or near the other end of the signal conductor of the first transmission line; a first open tip line (7), one of whose signal conductor constitutes open ends (8a, 8b) and the other end thereof constitutes an input end (9); and a second resistive element (10) which is connected at one end to the signal conductor of the first transmission line and connected at the other end to the input end of the first open tip line. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
