構成したことを特徴とするコードレス電話装置。 A cordless telephone device consists of a base unit equipped with a transceiver connected to a telephone line, and a handset connected to the base unit wirelessly, and the handset is connected to an outside line via the base unit. The separation circuit of the base unit that separates the call signal and control signal transmitted from the device is configured by providing a resonant circuit that resonates at the control signal frequency on the emitter side of the transistor whose base receives the received signal, and connects the collector of the transistor to the emitter side of the transistor. A cordless telephone device characterized in that it is configured to take out a control signal from the side and take out a voice signal from the emitter side.
