Abstract:
A front end circuit for coupling a plurality of antennas to a multi-channel time domain duplex RF transceiver is disclosed. The front end circuit has a first transmit port, a first receive chain primary port, a first receive chain secondary ports, and a first antenna port connectible to a first one of the plurality of antennas. The front end circuit also has a second transmit port, a second receive chain primary port, and a second receive chain secondary port connectible to a second one of the plurality of antennas. A first switch has terminals connected to the first transmit port, the first receive chain primary port, and the second receive chain secondary port, as well as a common terminal that is connected to the first antenna port. Additionally, the front end circuit has a second switch that has terminals connected to the second transmit port, the second receive chain primary port and the first receive chain secondary port, and a common terminal connected to the second antenna port.
