Paper Abstract

To meet the demands for higher efficiency and size, weight, power, and cost (SWaP-C), a high efficiency Power Amplifier (PA) design is discussed. The primary focus is on Class F and Inverse Class F PAs for increased efficiency in P, L, S, and X band applications. By incorporating innovative matching techniques at the second and third harmonics and including fast voltage switching circuits, efficiencies over 80% are achievable at a peak output power greater than 25 Watts. These technologies allow for a reduction in battery size and cooling requirements, while achieving state-of-the-art efficiencies.
