Bandwidth Extended Doherty Amplifier
The invention uses for the first time a paralleled right and left handed network in both impedance inverters. The proposed Doherty-like power amplifier (DLPA) is comprised of two ITs and two phase tuning lines for both the carrier and peaking devices, followed by a post matching network (PMN).
