ABSTRACT:
A strip-type second-harmonic-choking filter is constituted such that a main transmission line, through which a fundamental frequency wave is to be transmitted, is connected with first and second stub. The first stub exhibits a first susceptance value for the fundamental frequency and exhibits a subtantially infinite admittance value for a second harmonic of the fundamental frequency, on one side of said main transmission line. A second stub exhibits a second susceptance value which is essentially a conjugate of the first susceptance value for the fundamental frequency and exhibits an infinity or zero admittance value for the second harmonic frequency, at an opposite side of the transmission line from the first stub. For the fundamental frequency wave, the two stubs cancel the effects of each other so that no effect is given on the transmission of the fundamental wave, while one or both of the stubs choke the transmission of the second-harmonic wave. The stub may be bent so that more area is easily available for circuits to be installed on the same circuit board.
