ABSTRACT:
A MIMO transceiver integrated circuit (IC) includes a plurality of multiple band direct conversion transmitter sections, a plurality of multiple band direct conversion receiver sections, and a local oscillation generation module. Each of the plurality of multiple band direct conversion transmitter sections includes a transmit baseband module and a multiple frequency band transmission module. Each of the plurality of multiple band direct conversion receiver sections includes a multiple frequency band reception module and a receiver baseband module. The local oscillation generation module is operably coupled to generate the first frequency band local oscillation when the multiple band MIMO transceiver IC is in a first mode and operably coupled to generate the second frequency band local oscillation when the multiple band MIMO transceiver IC is in a second mode.
