RF transceiver architecture for flexible configuration of RF resources

摘要

One embodiment of the present invention provides a wireless transceiver. The transceiver includes a plurality of receiving paths, a plurality of transmitting paths, a number of RF components, and a configurable multiplexer for coupling one or more RF components to the transmitting paths and the receiving paths. The multiplexer is configured in such a way as to allow a particular RF component to couple to a subset of the receiving paths and/or a subset of the transmitting paths, thereby enabling flexible provisioning of the RF components.

1. A wireless receiver, comprising:
a plurality of receiving paths, wherein a particular receiving path can be configured to operate at a same or different frequency as that of a different receiving path, and wherein a particular receiving path includes at least one frequency mixer; a number of local oscillators; and a configurable multiplexer comprising a plurality of inputs and a plurality of outputs, wherein the plurality of inputs are coupled to the local oscillators, wherein the plurality of outputs are coupled to the plurality of receiving paths in a way that different outputs of the multiplexer are coupled to different receiving paths with each receiving path comprising an inphase signal path and a quadrature signal path, and wherein the multiplexer is configured in such a way as to allow a particular local oscillator to couple to frequency mixers of a subset of the plurality of receiving paths, thereby enabling flexible provisioning of the local oscillators.
