Webbranch line coupler ランチ・ライン・カプラ),「180°ハイブリッド」 (ラ rat race ット・レース)がよく知られています.マイクロ波 回路ではこれらを使って電力分配や電力合成が行わ れ,ミキサや移相器などの回路でよく応用されます. WebThe branch line coupler is a signal coupler or divider which has four ports. The geometry of the coupler is shown in Figure1. The signal fed to port 1 is split equally into port 3 and 4 with one of the outputs exhibiting a 90 phase shift. The port 2 is an isolated port. The design specifications of the coupler are shown in Table.1.
