Broadband distributed antenna system with non-duplexer isolator sub-system

摘要

Certain aspects and aspects of the present invention are directed to a distributed antenna system having a downlink communication path, an uplink communication path, and a non-duplexer isolator sub-system. The downlink communication path can communicatively couple a transmit antenna to a base station. The uplink communication path can communicatively couple a receive antenna to the base station. In one aspect, the non-duplexer isolator sub-system can be electronically configured for isolating uplink signals traversing the uplink communication path from downlink signals. In another aspect, a non-duplexer isolator sub-system can be configurable in one or more mechanical steps selecting a frequency response. In another aspect, a non-duplexer isolator sub-system can include an active mitigation sub-system.

主权项

1. A non-duplexer isolator sub-system for a distributed antenna system, the non-duplexer isolator sub-system comprising:
an electronically configurable filter positioned in at least one of:
a downlink path configured for communicatively coupling a transmit antenna of the distributed antenna system to a base station;an uplink path configured for communicatively coupling a receive antenna of the distributed antenna system to the base station; wherein the electronically configurable filter is configured for isolating the uplink path from downlink signals traversing the downlink path, wherein the electronically configurable filter is further configured for isolating the uplink path from downlink signals in a first frequency band in response to a first electronic control signal and is configured for isolating the uplink path from downlink signals in a second frequency band in response to a second electronic control signal.
