Abstract
Local oscillation circuitry for use in an RF transceiver Integrated Circuit (IC) includes local oscillation generation circuitry operable to produce a local oscillation and local oscillation distribution circuitry. The local oscillation distribution circuitry includes a splitting circuit, a first distribution portion, and a second distribution portion. The splitting circuit receives the local oscillation and produces multiple copies of the local oscillation. The first distribution portion produces a first local oscillation corresponding to a first RF band and a second local oscillation corresponding to a second RF band based and to provide the first local oscillation and the second local oscillation to a first RF transceiver group. The second distribution portion produces a first local oscillation and a second local oscillation and provides the first local oscillation and the second local oscillation to the second RF transceiver group.
