Abstract:
(EN) An impedance matching circuit (31) is provided with: inductors (311L and 312L) connected in series; a switch (311S) that has a first terminal and a second terminal, the first terminal being connected to one end of the inductor (311L), and that switches between conduction/non-conduction between the first terminal and the second terminal; a switch (312S) that has a third terminal and a fourth terminal, the third terminal being connected to a connection point between the other end of the inductor (311L) and one end of the inductor (312L), and that switches between conduction/non-conduction between the third terminal and the fourth terminal; and a switch (313S) that has a fifth terminal and a sixth terminal, the fifth terminal being connected to the other end of the inductor (312L), and that switches between conduction/non-conduction between the fifth terminal and the sixth terminal. The second terminal, the fourth terminal, and the sixth terminal are connected with each other.
(FR) Un circuit d'adaptation d'impédance (31) comprend : des inducteurs (311L et 312L) raccordés en série ; un commutateur (311S) qui comporte des première et deuxième bornes, la première borne étant raccordée à une extrémité de l'inducteur (311L), et qui commute entre conduction/non-conduction entre les première et deuxième bornes ; un commutateur (312S) qui comporte des troisième et quatrième bornes, la troisième borne étant raccordée en un point de raccordement entre l'autre extrémité de l'inducteur (311L) et une extrémité de l'inducteur (312L), et qui commute entre conduction/non-conduction entre les troisième et quatrième bornes ; et un commutateur (313S) qui comporte des cinquième et sixième bornes, la cinquième borne étant raccordée à l'autre extrémité de l'inducteur (312L), et qui commute entre conduction/non-conduction entre les cinquième et sixième bornes. Les deuxième, quatrième et sixième bornes sont raccordées les unes aux autres.
(JA) インピーダンス整合回路(31)は、直列接続されたインダクタ(311Lおよび312L)と、第1端子および第2端子を有し第1端子がインダクタ(311L)の一端に接続され第1端子と第2端子との導通および非導通を切り替えるスイッチ(311S)と、第3端子および第4端子を有し第3端子がインダクタ(311L)の他端とインダクタ(312L)の一端との接続点に接続され第3端子と第4端子との導通および非導通を切り替えるスイッチ(312S)と、第5端子および第6端子を有し第5端子がインダクタ(312L)の他端に接続され第5端子と第6端子との導通および非導通を切り替えるスイッチ(313S)と、を備え、第2端子と第4端子と第6端子とが接続されている。
