Multiple antenna system and transceiver front end for interband downlink carrier aggregation
Abstract:
A first antenna and a first band switch with a first duplexer operatively coupled to a first output of the first band switch. The first duplexer provides a transmit sub-band feed and a first receive sub-band feed for a first RF band. A second duplexer is operatively coupled to a second output of the first band switch, and provides a transmit sub-band feed and a first receive sub-band feed for a second RF band. A second antenna is operatively coupled to an input of a second band switch. A first antenna matching network for the second antenna is operatively coupled to a first output of the second band switch, and provides a second receive sub-band feed for the first RF band. A second antenna matching network is operatively coupled to a second output of the second band switch, and provides a second receive sub-band feed for the second RF band.
