Hybrid circuit for coupling a two-direction transmission path with a one-direction transmitting path and a one-direction receiving path, the arrangement comprising a first amplifier whose input is connected to the receiving path and whose output is connected to the two-direction transmission path, a second amplifier whose input is connected to the two-direction transmission path and whose output is connected to the transmitting path and a third amplifier whose input is connected to the receiving path and whose output is connected to the transmitting path, wherein the second amplifier is a direct-voltage differential amplifier and the first amplifier comprises a balanced direct-voltage-coupled output, while a damping network is connected between the two-direction transmission path and the input of the second amplifier.
