Pelk, M.J. (author), Neo, W.C.E. (author), Gajadharsing, J.R. (author), Pengelly, R.S. (author), De Vreede, L.C.N. (author)A three-way Doherty 100-W GaN base-station power amplifier at 2.14 GHz is presented. Simple, but accurate design equations for the output power combiner of the amplifier are introduced. Mixed-signal techniques are utilized for uncompromised control of the amplifier stages to optimize efficiency, as well as linearity. The combination of the above...journal article 2008
