1. A Radio Frequency (RF) transceiver Integrated Circuit (IC) comprising:

  • a first RF transceiver module that is operable to service communications within at least one RF band;

    a second RF transceiver module that is operable to service the communications within the at least one RF band, wherein the second RF transceiver module resides in substantial symmetry with the first RF transceiver module;

    local oscillation generation circuitry operable to produce a local oscillation; and

    local oscillation distribution circuitry coupled to the local oscillation generation circuitry, to the first RF transceiver module, and to the second RF transceiver module, the local oscillation distribution circuitry including;

    splitting circuitry operable to receive the local oscillation from the local oscillation generation circuitry and to produce multiple phase matched copies of the local oscillation;

    a first distribution portion coupled to the splitting circuitry and operable to produce a first local oscillation corresponding to the at least one RF band based upon the local oscillation and to provide the first local oscillation to the first RF transceiver module; and

    a second distribution portion coupled to the splitting circuitry and operable to produce a second local oscillation corresponding to the at least one RF band based upon the local oscillation and to provide the second local oscillation.
