摘要： 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.

摘要： An integrated circuit radio transceiver and method therefor includes an integrated circuit radio transceiver operable to provide pre-distortion settings that correspond to specified analog transmit path gain levels. Further, a change in gain is provided solely through digital gain when the new gain is within a specified range. If the gain change is not within the specified range, the gain is provided by a new transmit path gain module and, if necessary, with additional digital gain. Additionally, a new pre-distortion setting is applied to correspond to the new analog transmit path gain setting.

摘要： A wireless device includes an antenna, Radio Frequency (RF) circuitry, and baseband processing circuitry. The baseband processing circuitry couples to the RF circuitry and is operable to determine operational calibrations settings that may include pre-distortion characteristics and RF signal path settings, both of which are determined via calibration operations. The calibration operations are initiated when an operational value of the wireless device compares unfavorably to at least one operational threshold. Monitoring circuitry coupled to the RF circuitry and to the baseband processing circuitry monitors operational characteristics of the RF circuitry. Calibration operations may be initiated based upon RF circuitry temperature, supply voltage, PA current, PA gain input level/average, among other triggers.

摘要： A wireless device includes processing circuitry and Radio Frequency (RF) receiver and transmitter sections. An antenna transmits and receives a Radio Frequency (RF) Multiple Frequency Bands Multiple Standards (MFBMS) signal having a plurality of RF information signals within respective information signal frequency bands. The receiver/transmitter sections down-convert/up-convert between the RF MFBMS signal and a corresponding baseband/low Intermediate Frequency (BB/IF) information signal based upon at least one shift frequency. During receipt, the processing circuitry enables a set of information signal modules corresponding to the set of information signals to service receipt and extraction of data from the set of BB/IF information signals using the enabled set of information signal modules. During transmission, the processing circuitry enables a set of information signal modules corresponding to the set of information signals and produces an outgoing BB/IF MFBMS signal.
