感动女生的情话摘要：PURPOSE:To dispen with a transformer for a driving circuit for a push-pull amplifier circuit by applying pul processing to a circuit up to the input side of the push-pull amplifier circuit and by driving the push-pull amplifier circuit also by the pul processing. CONSTITUTION:Two pul trains being different in pha by 180 deg. are generated by a pul generating circuit 35. The two pul trains are supplied to the two input terminals of an output push-pull amplifier circuit 22 through different variable voltagedividing circuits 44 and 45 respectively. On the other hand, a transmission-reception switching circuit 53 is connected to the condary side of an output transformer 29 of the push-pull amplifier circuit 22. By this constitution, a transformer can be omitted from a driving circuit for the output push- pull amplifier circuit 22, and thereby the device can be made less expensive.
