Abstract:
1. A MIMO radio transceiver integrated circuit (IC) comprising: a first transmitter and a first receiver, each of which includes an in-phase (I) signal path and a quadrature (Q) signal path; a second transmitter and a second receiver, each of which includes an in-phase (I) signal path and a quadrature (Q) signal path; a first transmitter connection pin on which a transmit I signal and a transmit Q signal are multiplexed for connection to the respective I and Q signal paths of the first transmitter; a second transmitter connection pin on which a transmit I signal and a transmit Q signal are multiplexed for connection to the respective I and Q signal paths of the second transmitter; a first receiver connection pin on which a receive I signal and a receive Q signal are multiplexed from the respective I and Q signal paths of the first receiver; and a second receiver connection pin on which a receive I signal and a receive Q signal are multiplexed from the respective I and Q signal paths of the second receiver.
