RADIO FREQUENCY TIME SKEW CALIBRATION SYSTEMS AND METHODS

摘要

Systems and method for improving operation of a radio frequency system are provided. One embodiment provides a radio frequency system that includes an amplifier device with a first data path and a second data path. Additionally, the radio frequency system includes a controller that instructs the radio frequency system to transmit a calibration signal, which includes a first portion that excites the first data path and a second portion that excites the second data path; determines time skew between the first and second data paths based at least in part on phase shift between a first sample of a feedback signal and the first portion, phase shift between a second sample of the feedback signal and the second portion, or both; and instructs the radio frequency system to adjust delay applied on the first data path, the second data path, or both based at least on the time skew.
