摘要:
A wireless device includes processing circuitry, a receiver section, a transmitter section, and an antenna. The processing circuitry determines a set of information signals of a RF Multiple Frequency Bands Multiple Standards (MFBMS) signal. The receiver section includes a plurality of receive paths, each having down-conversion circuitry that down-converts a portion of the RF MFBMS signal by a respective shift frequency to produce a corresponding baseband/low Intermediate Frequency (BB/IF) information signal. A combiner combines the plurality of BB/IF information signals to form a BB/IF MFBMS signal, from which the processing circuitry extracts data. The transmitter section includes a plurality of transmit paths, each having up-conversion circuitry operable to up-convert a respective BB/IF information signal received from the processing circuitry by a respective shift frequency to produce a corresponding RF information signal and a combiner that combines the RF information signals to form a RF MFBMS signal.
