Abstract

PURPOSE:To reduce the impedance conversion loss by curtailing a middle part of a tapered impedance conversion part at a connection part from a transistor(TR) chip in a microstrip line into a proper shape. CONSTITUTION:A gate electrode of a TR chip 4 of a high frequency high output TR is connected to an impedance conversion section 8 of an internal matching circuit 20 for gate, then a microstrip line 5. A drain electrode or the TR chip 4 is connected to a strip line 6 via an impedance conversion section 2 of an internal matching circuit 10 for drain. Moreover, the internal matching circuit board 10 has the microstrip line 6 made of a metallic pattern and a tapered impedance conversion section 2. Then an opening 1 is provided to the middle of the tapered impedance conversion part 2, a difference from the electric length of each path at the tapered impedance conversion part is minimized by the opening 1.
