Patent ID: 8463217

Claim:
A multiple band multiple input multiple output (MIMO) transceiver integrated circuit (IC) comprises: a plurality of multiple band direct conversion transmitter sections, each of the plurality of multiple band direct conversion transmitter sections including: transmit baseband module configured to receive an outbound baseband signal and to produce a processed outbound baseband signal; and a multiple frequency band transmission module configured to: when the multiple band MIMO transceiver IC is in a first mode, convert the processed outbound baseband signal into a first outbound radio frequency (RF) signal having a first RF carrier frequency within a first frequency band in accordance with a first frequency band local oscillation; and when the multiple band MIMO transceiver IC is in a second mode, convert the processed outbound baseband signal into a second outbound RF signal having a second RF carrier frequency within a second frequency band in accordance with a second frequency band local oscillation; a plurality of multiple band direct conversion receiver sections, wherein each of the plurality of multiple band direct conversion receiver sections include: a multiple frequency band reception module configured to: when the multiple band MIMO transceiver IC is in the first mode, convert a first inbound RF signal having the first RF carrier frequency into an inbound baseband signal in accordance with the first frequency band local oscillation; and when the multiple band MIMO transceiver IC is in the second mode, convert a second inbound RF signal having the second RF carrier frequency into the inbound baseband signal in accordance with the second frequency band local oscillation; and a receiver baseband module configured to receive the inbound baseband signal to produce a processed inbound baseband signal; and a local oscillation generation module configured to: provide the first frequency band local oscillation when the multiple band MIMO transceiver IC is in the first mode; and provide the second frequency band local oscillation when the multiple band MIMO transceiver IC is in the second mode, wherein either of the first frequency band local oscillation or the second frequency band local oscillation is provided as a multiplexed output in accordance with the first mode and the second mode.
