Abstract

PURPOSE:To obtain a balanced output from a signal switching circuit having positive and negative polarities and to improve the impedance matching of input and output side, by connecting a transformer for the input and output side respectively and connecting diodes and resistors between the transformer and the power supply. CONSTITUTION:A control voltage is supplied to terminals 19A, 19B with opposite polarity, and a current flows to a diode 13A from a terminal 17, when a negative voltage is given to the terminal 19A, a diode 12A is reverse-biased, and when a bipolar signal is inputted from the input 1 side, a diode 11 is biased with a negative power supply -E2 for conduction. When a positive voltage is given to the terminal 19A, the diode 13A is reverse-biased, a current flows to the negative power supply -E2 via the diode 12A from a positive power supply E1, the diode 11A is reverse-biased and a signal from the input 1 turns off. A signal of the input 1 appears when the terminal 19A is negative and the terminal 19B is positive, and the signal at the input 2 appears at the output when opposite polarity.
