Abstract
This paper outlines the use of a measurement based waveform CAD tool for enhanced PA design. Two measurement based models have been used to simulate a complete Doherty power amplifier together with output matching. The output matching network and auxiliary bias were optimised to produce a region of high efficiency typical of Doherty power amplifiers. Through the incorporation of a large signal de-embedding network, the current and voltage waveforms were accessed at the current generator plane. This allowed for the confirmation of Doherty operation on an individual device basis. This powerful tool allows for further optimisation of power amplifiers using well established waveform design procedures, previously not possible at high power levels.
