送受信装置。[Claims for Utility Model Registration] (1) A modulation circuit that modulates a transmission signal from a binary data transmission source into a form suitable for superimposing it on a power supply line; and amplifying the modulated data signal modulated by the modulation circuit. an amplifier circuit that allows only signals within a predetermined frequency band based on the frequency band of the amplified modulated data signal to pass from a first terminal toward a second terminal; a bidirectional bandpass filter that also allows a signal to pass from the second terminal to the first terminal, if any; an input/output terminal connected to the second terminal of the bidirectional bandpass filter; and the bidirectional bandpass filter. A transmitting/receiving device comprising: a demodulation circuit connected to a first terminal of a filter; (2) A bidirectional bandpass filter has its first and second terminals connected by a simple line, or consists of the same circuit point, and is connected between the line or circuit point and a reference potential. 2. The transmitting/receiving device according to claim 1, which is a utility model registration device, characterized in that the transmitting/receiving device comprises a parallel circuit of an inductor and a capacitor.
