About this document
Outphasing Microwave Amplifier Efficiency by JJ Wu is a document available to read on EtoBox.
This paper presents a new analysis of the efficiency and linearity of Chireix-outphasing combiners, highlighting the impact of impedance mismatch on performance. The authors derive new expressions for output voltages and instantaneous efficiency, demonstrating that impedance mismatch is a primary cause of nonlinearity in these amplifiers. Various simulations validate the derived equations, showing a quasi-exact agreement and emphasizing the importance of combiner parameters on linearity and efficiency.
