Abstract

PURPOSE:To prevent the whole size from becoming a large size by adjusting a variable length open stub to length by which a characteristic which has seen a terminal side of a bias circuit from a common connecting part of two matching impedance lines can correct the impedance matching by a matching circuit. CONSTITUTION:A bias circuit 20 for an active element sets an open stub 24 to variable length, and also, between a common connecting part 34 of a first high impedance line 22 and a variable length open stub 24, and a terminal resistance 26, a second high impedance line 36 is provided. Also, a characteristic impedance when the terminal resistance side has been seen from a connecting point 40 of a transmission line 38 and the bias circuit 20 for active element is determined by length or width of the first and second high impedance lines 22, 36, or a resistance value of the terminal resistance 26, but according to this constitution, the characteristic impedance is adjusted by adjusting the length of the variable length open stub 24. In such a way, a high frequency circuit can easily be integrated.
