摘要： PROBLEM TO BE SOLVED: To provide a communication system for stably reducing the signal level of a loopback signal.
SOLUTION: A magnitude relation between the impedance of the total of resistances R1 and R2 for impedance matching between a transmitting part 10 and a transmission line C20 and the characteristics impedance of a transmission line C20 and a magnitude relation between the impedance of the total of resistances R3 and R4 for impedance matching, between the transmitting part 10 and a terminal resistance RT and the impedance of the terminal resistance RT are matched in the frequency range of the signal to be transmitted/received by a hybrid circuit 1. Thus, since phase change at reflection between the transmission line C20 and phase change at reflection between the terminal resistance RT can be made the same, and differential components are taken by a receiving part 11 so that components due to reflection can be offset at the two parts the voltage level of a loopback signal can be stably suppressed low.
