Summary:PROBLEM TO BE SOLVED: To achieve a harmonic processing circuit capable of improving a reflection amplitude of harmonics and improving efficiency in a transistor.SOLUTION: A harmonic processing circuit includes an open ended stub 17 which forms a short circuiting point with respect to the n-th harmonic of a high frequency signal flowing through a main line 16. A via 18 is configured so as to connect the open ended stub 17 and the main line 16 at a position shifted from a center 16e of the main line 16 in a line width direction. Therefore, it is possible to improve a reflection amplitude of the n-th harmonic and to improve efficiency in a transistor 1.SELECTED DRAWING: Figure 3 【課題】高調波の反射振幅を高めて、トランジスタの効率を高めることができる高調波処理回路を得ることを目的とする。【解決手段】主線路１６を流れる高周波信号のｎ次の高調波に対して短絡点を形成する先端開放スタブ１７を備え、ビア１８が、主線路１６における線路幅方向の中心１６ｅからずれている位置で、先端開放スタブ１７と主線路１６を接続するように構成する。これにより、ｎ次の高調波の反射振幅を高めて、トランジスタ１の効率を高めることができる。【選択図】図３
