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： An integrated circuit (IC) includes a clock circuit, a processing module, and processing circuitry. The clock circuit is coupled to produce a digital clock signal. The processing module is coupled to determine whether a harmonic component of the digital clock signal having a nominal digital clock rate is within the frequency passband and to provide an indication to the clock circuit to adjust its rate from the nominal digital clock rate to an adjusted digital clock rate when the harmonic component of the digital clock signal is within the frequency passband. The processing circuitry is coupled to process, at the adjusted digital clock rate, the data to produce processed data having a rate corresponding to the nominal digital clock rate and to interpolate, at an interpolation rate, the processed data to produce interpolated processed data having a rate corresponding to the interpolation rate.

摘要： Communication processing paths include distortions, such as DC offset in the baseband analog path, local oscillator feed-through distortion, and nonlinearity of gm's and power amplifiers which are calibrated for, separately or in combination. The cascaded DC offset and nonlinear distortions are modeled separately or in combination using even-and-odd order polynomials. A loopback path from the output of one or more distortion causing devices passes through a measurement and calculation module. The calculation module calculates predistortion polynomial's coefficients which will be stored in a look-up table to be used by a baseband predistorter to calibrate the path. The look-up table is stored locally or remotely.

摘要： Transmitter calibration of a wireless device is initiated based upon an operational value of the wireless device. The calibration operations are performed over a plurality of calibration time periods, each calibration time period divided into a plurality of first interval portions interspersed with a plurality of second interval portions, for each calibration time period of the plurality of calibration time periods, respective calibration settings are applied. During the first interval portions substantially fixed first current input is applied to at least one gain adjustable element of the RF circuitry. During the second interval portions, varying current input is applied to the at least one gain adjustable element of the RF circuitry. Output levels of the RF circuitry are measured over the calibration time period. Operational calibration settings for the baseband processing circuitry and analog signal path components of the transmitter are selected based upon the calibration operations.
