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 radio transceiver comprises an integrated phase shift mixer for generating a phase and frequency shifted output signal to at least a portion of one of a transmitter or receiver front end. The integrated phase shift mixer includes a phase shift block that is operable to produce a phase shifted current signal at an output of the phase shift block and a mixer that is operable to produce the phase and frequency shifted output signal based upon the phase shifted current signal. One aspect of the present invention is that the phase shift block produces an output as a current signal and the mixer block is operably disposed and formed to receive the current signal produced by the phase shift block. Thus, the mixer includes a folded cascode mixer that provides a substantially low input impedance.
