Local oscillation routing plan applicable to a multiple RF band RF MIMO transceiver

Local oscillation circuitry formed in a Radio Frequency (RF) transceiver Integrated Circuit (IC) that includes a first RF transceiver group that is operable to service both a first RF band and a second RF band and a second RF transceiver group that is operable to service both a first RF band and a second RF band, the local oscillation circuitry comprising:

• local oscillation generation circuitry operable to produce a local oscillation;
• and
• local oscillation distribution circuitry operably coupled to the local oscillation generation circuitry, to the first RF transceiver group, and to the second RF transceiver group, the local oscillation distribution circuitry comprising:
• a splitting circuit operable to receive the local oscillation from the local oscillation generation circuitry and to produce multiple copies of the local oscillation;
• a first distribution portion coupled to the splitting circuit and operable to produce a first local oscillation corresponding to the first RF band based upon the local oscillation, to produce a second local oscillation corresponding to the second RF band based upon the local oscillation, and to provide the first local oscillation and the second local oscillation to the first RF transceiver group;
• and
• a second distribution portion coupled to the splitting circuit and operable to produce a first local oscillation corresponding to the first RF band based upon the local oscillation, to produce a second local oscillation corresponding to the second RF band based upon the local oscillation, and to provide the first local oscillation and the second local oscillation to the second RF transceiver group.
