    Abstract: 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 down-converts a portion of the RF MFBMS signal by one or more respective shift frequencies to produce a corresponding baseband/low Intermediate Frequency (BB/IF) information signal from which the processing circuitry extracts data. The transmitter section converts 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. The receiver section and the transmitter section include ADCs and/or DACs, respectively, that are adjustable based upon characteristics of the RF MFBMS signal, the BB/IF MFBMS signal, and/or based upon signals carried therein, e.g.

  • Publication number: 20120307876
    Abstract: Analog signal paths are utilized between a baseband processor and a radio front end to support high throughput communications for a multiple in multiple out radio transceiver that support communications over two or more antennas. Specifically, analog differential I and Q path communication signals are exchanged between a radio front end core and a baseband processor to maximize throughput capacity for high data rate signals. Along the same lines, the impedances of traces and the interface are matched to reduce I/Q imbalance.
