Dynamic load modulation of high power amplifiers with varactor-based matching networks

• In this paper, the results of dynamic load modulationon a high power amplifier is shown with experiments. Asimple static nonlinear model is used as an inverse model, andby dynamically controlling both the input signal to the poweramplifier and the load impedance, high efficiency operation ofthe power amplifier is achieved. The modulated measurementsshow the feasibility of dynamic load modulation for practicalhigh power, high frequency applications.
