Designing a simultaneously linear and efficient radio-frequency (RF) power amplifier (PA) is no simple task. The Microwave Theory and Techniques Technical Committee on The High-Power Amplifier Components (MTT-5), aiming to promote this challenge at the student level, organized the ninth version of its annual high efficiency PA contest at the 2013 IEEE Microwave Theory and Techniques Society (MTT-S) International Microwave Symposium (IMS2013). Built upon our participation in 2012, the 3.5‐GHz linear Doherty PA design was only slightly modified in response to a change in the gain requirement of this year’s competition rules.
