摘要： Embodiments of methods and means for calibrating a linearization characteristic within an RF transceiver system are provided. Such embodiments generally include extracting a portion of an output signal and frequency shifting or translating that signal by a predetermined value. The frequency shifted signal is then summed or otherwise introduced into a receiver signal pathway where it is analyzed by digital signal processing or other means to determine if linearization distortion is present. Linearization calibration of a power amplifier, a low-noise amplifier and/or other functionality within the system can then be performed in an automatic, reliable and ongoing manner.

摘要： A multichip transceiver operates as part of a multiple-input multiple-output communication system. First receiver circuitry on a first integrated circuit processes radio-frequency (RF) signals received from a first signal source, and second receiver circuitry on a second integrated circuit processes RF signals received from a second signal source. Clock-signal generating circuitry provides clock signals through phase-matched paths to the first and second receiver circuitry.
