Abstract
A 50 W S-band High Power Amplifier in the UMS GH25-10 technology is presented. In order to increase the output power per area the size of the transistors is increased beyond the maximum size modelled by the foundry. For this reason the design procedure included the measurements of a transistor and the creation of a scalable Angelov-GaN model with the use of EM simulations. An output matching design approach is adopted which intrinsically optimizes the transistor harmonic load impedance. The results show that the amplifier delivers an output power of over 50 W within the frequency range from 3.05 to 3.5 GHz at a PAE of more than 62 %. The maximum measured output power is 63 W with a PAE of 65 %.© 2014 European Microwave Association.
