PURPOSE:To prevent crosstalk by biasing plural analog signals at a different DC voltage. CONSTITUTION:An analog signal inputted to input signal terminals 1, 2 is added by bias voltages +V1, -V2 at DC bias adding circuits 15, 16 and the result is applied to a base of transistors (TRs) 17, 20 via low pass filters 3, 4. Then TRs 18, 19 are conductive corresponding to positive and negative polarities of an output of a clock oscillator 6 so as to transmit the analog signal applied to the base of the TRs 17, 20 to a transmission line l. |
