How To Characterize Power Amplifier Modulated Signal Distortion
Characterizing power amplifier modulated signal distortion with a VNA
Characterizing a power amplifier (PA) to ensure compliance with 5G New Radio (NR) standards requires wideband, calibrated vector signal generation and signal analysis. A single testbed with a vector network analyzer (VNA), vector signal generator, and multiple measurement software applications provides fully-calibrated signal generation at the PA input.
The measurement software applications enable accurate adjacent channel power ratio (ACPR) and low residual error vector magnitude (EVM) measurements directly on the VNA. During testing, the engineer operates multiple measurement applications without changing the configuration of the test setup.
