Qureshi, J.H. (author), Pelk, M.J. (author), Marchetti, M. (author), Neo, W.C.E. (author), Gajadharsing, J.R. (author), Van der Heijden, M.P. (author), De Vreede, L.C.N. (author)A 90-W peak-power 2.14-GHz improved GaN outphasing amplifier with 50.5% average efficiency for wideband code division multiple access (W-CDMA) signals is presented. Independent control of the branch amplifiers by two in-phase/quadrature modulators enables optimum outphasing and input power leveling, yielding significant improvements in gain,...journal article 2009

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
