4 Triple-Band CFR/DPD Performance Test Results

For each tested channel, the Adjacent Channel Leakage Ratio (ACLR) and Error Vector Magnitude (EVM%) results at the PA outputs are shown. In the collected ACLR performance plots, the orange curves show the ACLR performance before the DPD is applied, and the blue curves shows the ACLR performance after the using the AFE7769D integrated DPD algorithm to linearize the PA.
