摘要:
A Radio Frequency (RF) transceiver Integrated Circuit (IC) includes a plurality -of RF transceivers, local oscillation generation circuitry that produces a local oscillation, and local oscillation distribution circuitry. The local oscillation distribution circuitry couples to the local oscillation generation circuitry and includes a plurality of local oscillation repeater circuits. Each local oscillation repeater circuit corresponds to a respective one of the plurality of RF transceivers (transmitter, receiver, or both) Each local oscillation repeater circuit includes a local oscillation repeater circuit input, a local oscillation repeater circuit interface driver output coupled to respective one of the plurality of RF transceivers, and a local oscillation repeater circuit output. Each local oscillation repeater circuit also includes a first driver having as an input the local oscillation repeater circuit input and as an output the local oscillator repeater circuit output and a second driver having as an input the local oscillation repeater circuit input and as an output the local oscillation repeater circuit interface driver output.
