Filed: 1986-04-23
Abstract: PURPOSE:To reduce voltage loss by differentiating the constitutions of respective phase shifters connected to the input side and output side respectively so that the impedance in the device on the input side is smaller than that of the output side. CONSTITUTION:The constitutions of the phase shifters connected to respective electrodes 2, 3 on the input and output sides are differentiated from each other. Namely, the input side is constituted by connecting a reflecting electrode 10 to an inductor 5 in series, earthing a meander-like electrode 11 and connecting said serial connection to the electrode 11. On the other hand, the output side is constituted by connecting an inductor 6 in parallel between a sending electrode 12 and a meander-like electrode 14, connecting an inductor 7 in parallel between a reflecting electrode 13 and the electrode 14, earthing the electrode 13 and connecting these electrodes in series. Since the internal impedance ratios are made different and the phase shifters are used so that the ratio of the input side is smaller than that of the output side, the internal impedance of the input side can be reduced so as to be smaller than that of the output side and the voltage loss can be reduced.
