Radio Frequency Time Skew Calibration Systems and Methods

摘要

Systems and methods are provided for improving the operation of a radio frequency system. One embodiment provides a radio frequency system comprising an amplifier device having a first data path and a second data path. Additionally, the radio frequency system instructs the radio frequency system to transmit a calibration signal comprising a first portion to excite the first data path and a second portion to excite the second data path; The time between the first and second data paths based at least in part on the phase shift between the first sample and the first portion of the feedback signal, the phase shift between the second sample and the second portion of the feedback signal, or both. Determine the skew; A controller instructing the radio frequency system to adjust a delay applied on the first data path, the second data path, or both based at least on time skew.
