Basic RF Amplifier Measurements using a Vector Network Analyzer

This Application note discusses the effective characterization and optimization of RF amplifier parameters such as S-parameters, return loss, gain, isolation, impedance and stability. Non-linear measurements including compression points, harmonics, intermodulation products and intercept points, and Amplitude Modulation to Phase Modulation (AM-PM) conversion are also addressed. Measurements are being performed using an R&S®ZNB Vector Network Analyzer.
