Abstract

PURPOSE:To prevent a shape of a matching circuit and a coupling line from becoming a large size, by selecting the line length of a high impedance line of a bias circuit and an open stub, to prescribed length and allowing it to have a finite impedance. CONSTITUTION:A bias circuit 26 is constituted of a first high impedance line 28 having prescribed lien length l4 (other length than lambda/4), whose one end has been connected to the end part of a first microstrip line 22 of a coupling line 16, an open stub 30 having prescribed line length l5 (other length than lambda/4), which has been connected to the other end of the first high impedance line 28, a second high impedance line 32 having prescribed line length, and a terminal resistance 34 which has been connected to the second high impedance line 32. Accordingly, by selecting suitably the line length l4 of the first high impedance line 28 and the line length l5 of the open stub 30, an impedance Za can be determined. In such a way, it is prevented that a shape of a matching circuit 10 and the coupling line 16 becomes a large size.
