There is growing interest in parallel transmit architectures and in the use of low cost systems that may display significant non-linearity in response. We describe a system level calibration approach that can generate a full set of calibration tables for multi-channel RF systems. The method is simple to set up and provides compensation for frequency drifts during the calibration process.
