PURPOSE:To reduce not only the number of component parts but the mon-hours, by connecting a coil and a resistance of a parallel connection to a double winding transformer in which each end of two windings having an equal winding number is connected to each other with another end of each winding connected to each other via a capacitor. CONSTITUTION:A phase shifter consists of a double winding transformer 7 in which each end of two windings having an equal winding number is connected to each other with the other end of each winding connected to each other via a capacitor 6, a coil 8 connected to an end of the transformer 7, and a resistance 9 connected in parallel to the coil 8. As the coil 8 is connected in parallel to the resistance 9, an increment of impedance can be prevented at the area of connection of the coil and resistance at a high level of frequency. |
