Patent ID: 8014820

Claim:
A multiple-in multiple out (MIMO) radio transceiver, comprising: a baseband processor; a plurality of front end cores, each front end core further including: a first Rx/Tx processing block further includes: first receive in-phase and quadrature phase differential signal paths; first transmit in-phase and quadrature phase differential signal paths; a second Rx/Tx processing block further includes: second receive in-phase and quadrature phase differential signal paths; and second transmit in-phase and quadrature phase differential signal paths; and wherein each of the first and second Rx/Tx processing blocks for each of the plurality of front end cores are operable to process differential signals received from and transmitted to the baseband processor according to whether the differential signal is received from the baseband processor by a differential transmit path or is transmitted to the baseband processor from a differential receive path.
