  • Parallel hybrid circuit
    Patent number: 9065546
    Abstract: A parallel hybrid circuit comprising a transformer, a first matching resistor, a second matching resistor and an echo cancelling circuit. The transformer comprises: a first side, comprising a transmitting coil group and a receiving coil group, wherein the transmitting coil group comprises at least one transmitting coil, wherein the receiving coil group comprises at least one receiving coil; a second side comprising at least one transceiving coil; wherein the transformer receives a transmitting signal and couples the transmitting signal from the first side to the second side via a first turn ratio, and receives a receiving signal from the transceiving line and couples the receiving signal from the second side to the first side via a second turn ratio. The first, second matching resistors are coupled with the transformer in parallel. The echo cancelling circuit is coupled between the transmitting line and the receiving line.
