Optimization Design of Broadband Doherty PA Using Fragment-Type Matching Network Based on Dual-State Impedance Objective Function

In this paper, an optimization design of broadband Doherty power amplifier (DPA) is presented for the extension of bandwidth. A dual-state impedance objective function is utilized in the optimization of the carrier and peaking output matching networks (OMNs) to satisfy the load impedance constraints...
