摘要： Parallel capacitors (5c and 5d) of impedance matching circuits (5) which are connected to two transistors (1), respectively, have their first ends connected to a ground through via holes (5e and 5f) that are used in common, respectively. Although a conventional circuit necessitates via holes by the number equal to the number of stages multiplied by the number of cells of the transistors (1) for an LPF type impedance matching circuit (3), the present circuit can halve the number of via holes of the LPF type impedance matching circuit (5), thereby being able to downsize the circuit.

摘要翻译： 分别连接到两个晶体管（1）的阻抗匹配电路（5）的并联电容器（5c和5d）分别通过通孔（5e和5f）分别连接到地面。 尽管常规电路需要通孔数等于与LPF型阻抗匹配电路（3）的晶体管（1）的单元数相乘的级数，但本电路可以将通孔的数量减半 LPF型阻抗匹配电路（5），从而能够使电路小型化。
