Abstract
Hybrid frequency compensation is provided. Hybrid circuits are used to subtract the transmit signal from the receive signal in a full duplex communication system. Since the hybrid circuit and the main line driver are exposed to different loads, accurate subtraction is difficult to achieve. A frequency dependent network is used to match the loading seen by the driver and the hybrid. The compensation network can be based on active and/or passive components.
