PURPOSE:To change the insertion loss and coupling loss, by connecting the secondary coil connected between an input terminal and main line output terminal to a branch output terminal, and connecting a resistor with the input terminal. CONSTITUTION:The primary coil 7 of a transformer 6 is connected between an input terminal 3 of a branch circuit 2 and a main line output terminal 4, one terminal of the secondary coil 8 being at opposite polarity as the coil 7 is connected to a branch output terminal 5, and another terminal is grounded. A resistance means 9 which can change the resistance value is connected between the input terminal 3 and the branch output terminal 5. High frequency signals from a high frequency signal source 1 flows from the input terminal 3 to the primary coil 7 and gives to a load 13 from the terminal 4, and the high frequency signal induced in the secondary coil 8 is given to a receiver 14 from the terminal 5 together with the high frequency signal from the means 9. |
