Abstract

This paper presents a systematic design technique for a wideband GaN HEMT Class-J Doherty amplifier based on the second harmonic tuning. Following a theoretical explore on the expanded design space for a dynamic load modulation, the output matching networks of both Carrier and Peaking amplifiers are synthesized to satisfy the Class-J load requirement. A wideband Class J DPA with a symmetrical architecture is designed as a proof-of-concept to operate over a 1.5 to 3.2 GHz band frequency and delivers 40%-47% power added efficiency.
