A New Approach to Load Pull

White Paper Overview 

RF frontends and amplifiers are increasingly tested under realistic operating conditions. Load pull is a common technique to understand the behavior of RF frontends with varying conditions and matchings in the target application, optimize the DUT or create accurate models. Traditionally, load pull relies on continuous wave signals to look at the device behavior. With increasing signal bandwidths, modulated signals are being used more and more in load pull environments. This paper explores practical use-cases and a new method to run load pull testing with modulated signals.
