摘要:
A configurable transceiver and method of operation are disclosed that may dynamically switch between a direct-conversion mode and a direct-sampling mode based, at least in part, upon a frequency component of a receive and/or transmit signal. When in the direct-conversion mode, the transceiver may operate as a direct-conversion transceiver, and when in the direct-sampling mode, the transceiver may operate as a direct-sampling transceiver. For some embodiments, a frequency of the receive signal and/or the transmit signal may be compared with a predetermined frequency threshold value to generate a mode signal, and the mode signal may be used to select between the direct-conversion mode and the direct-sampling mode.
