摘要：Certain features relate to a remote antenna unit having a multi-stage isolationsub-system for isolating uplink and downlink signal paths. A multi-stage isolation sub-system in the remote antenna unit can include a first stage device that is configured to
generate a cancellation signal for canceling unwanted downlink signals received at theuplink antenna. The isolation sub-system can also include a second stage deviceconfigured to generate a cancellation signal that attenuates residual noise and
intermodulation products generated in the downlink path and received in the uplink path.The multi-stage isolation sub-system can combine the cancellation signals with signalsreceived on the uplink path in order to cancel or attenuate downlink leakage signals andresidual noise present on the uplink path.
