This book describes a measurement system that was set to perform comprehensive measurements on RF power amplifiers. Data obtained from the measurements is then processed mathematically to plot 3D graphs of the basic parameters affected or generated by nonlinearities of the amplifier i.e. gain, efficiency and distortion .Using a class AB amplifier as the DUT, two sets of signals ? both swept in power level and frequency were generated to validate the method; a twotone signal and a WCDMA signal. The measurement setup yields 3D plots of variations of gain, efficiency or distortion versus any arbitrary range of frequencies and input levels. Moreover, the measurement tool can be used to plot traditional 2D plots. The test signals were generated by computer then sent to a vector signal generator that generates the actual signals fed to the amplifier. The output of the amplifier is fed to a vector signal analyzer then collected by computer to be handled. MATLAB was used throughout the entire process. The system can be a very useful tool for RF amplifier users and designers. It is also useful for students who are working to understand RF amplifiers and their common tradeoffs.
