Singh, G.D. (author), Nemati, Hossein Mashad (author), Alavi, S.M. (author), de Vreede, L.C.N. (author)This paper proposes a power amplifier (PA) correction technique to recover from load mismatch. It utilizes a main PA, two auxiliary PAs, and a coupler. By adjusting the input drive levels of the PAs it can recover the output power and to a great extent the efficiency of the main PA even when exposed to 2:1 VSWR mismatch conditions. When...conference paper 2023
