Abstract
Disclosed herein are implementations of a hybrid network for use in a full duplex communication system. In one aspect, the hybrid network includes a first circuit coupled between an output of a communication channel and a shared output of a transmitter and the communication channel, a second circuit coupled between a first output of the transmitter and the shared output, a third circuit coupled between the shared output and an input of an amplifier, a fourth circuit coupled between the input of the amplifier and a second output of the transmitter, and a fifth circuit coupled between an output of the amplifier and the input of the amplifier. In some embodiments, the output of the amplifier is coupled to an input of a receiver.
