The Doherty power amplifier (PA) configuration offers a cost-effective solution for achieving a low distortion yet efficient amplifier. To properly design a Doherty PA, RF engineers need an understanding of how these devices work, along with suitable RF circuit simulation technology such as Cadence® AWR Design Environment® software and accurate device models.

This webinar, presented jointly by Dr. Osman Ceylan of Maury Microwave and David Vye of Cadence, overviews a Doherty PA theory, as well as a turnkey measurement-to-model flow based on Maury Microwave and AMCAD Engineering load-pull and enhanced poly-harmonic distortion (EPHD) models.  In addition, the process used to design and validate a Doherty PA will be described, including measurements, model extraction, circuit design, circuit fabrication, and, finally, validation measurements to demonstrate first-pass design success.
