High-Power Amplifier Characterization using a Nonlinear Vector Network Analyzer
High-power amplifiers are commonly found in communications handsets and base stations where the maximum power levels may range from 1W to well over 100W. The characterization of such high-power amplifiers can be very challenging due to their nonlinear performance and the high power levels involved. A vector network analyzer (VNA) may be used to measure the S-Parameters, IMD, compression, and other characteristics of such devices if the VNA test set is modified to output and receive high power levels. However, for high-power amplifiers a nonlinear vector network analyzer (NVNA) should be used to accurately characterize both the linear and nonlinear behavior of the amplifier. This will result in a more complete characterization of the amplifier and shorten the design cycle. This webcast will describe the key values of nonlinear vector network analysis and will discuss various NVNA configurations and calibration techniques to handle high-power devices without damaging the network analyzer and sacrificing measurement accuracy.
