Abstract
Load mismatch becomes an urgent issue to be resolved in the design of RF PA circuit with the fast development of wireless communication technology. In this paper, we proposed a real-time waveform load pull technique for RF PA ruggedness test, which can be used for both fundamental and harmonic load mismatch and deliver accurate output waveforms. This technique has many advantages versus traditional passive load pull based techniques. Through rigorous experimental verification, it is proved that this technique is capable of providing comprehensive and meaningful information for the RF circuit Electro-Magnetic safety analysis and design.
