1. A multiple-input multiple-output (MIMO) radio transceiver on a single semiconductor integrated circuit, comprising:

  • a. a receiver comprising at least first and second receiver circuits each to process a signal from a corresponding one of first and second antennas, the first receiver circuit downconverts a first receive signal detected by the first antenna to produce a first baseband signal, the second receiver circuit downconverts a second receive signal detected by the second antenna to produce a second baseband signal; and

    b. a transmitter comprising at least first and second transmitter circuits, the first transmitter circuit upconverts a first baseband transmit signal to generate a first radio frequency signal that is coupled to the first antenna for transmission, the second transmitter circuit upconverts a second baseband transmit signal to generate a second radio frequency signal that is coupled to the second antenna for transmission.
