| Zusammenfassung: | A directional coupler (1) is provided with: a main line (10); a sub-line (20) electromagnetically coupled to the main line (10); a coupling output terminal (40); a first filter connected to one end (21) of the sub-line (20); and a second filter which is connected to one end (21) of the sub-line (20) and the coupling output terminal (40), and which has a passband different from that of the first filter. The first filter and the second filter form a multiplexer. The first filter is terminated.
定向耦合器(1)具备：主线路(10)；副线路(20)，与主线路(10)电磁耦合；耦合输出端子(40)；第一滤波器，与副线路(20)的一端(21)连接；以及第二滤波器，与副线路(20)的一端(21)和耦合输出端子(40)连接，且通带与第一滤波器不同。第一滤波器和第二滤波器构成多工器。第一滤波器被终端化。 |
