This paper proposes a design methodology for dual-band Doherty power amplifier (DPA) with performance enhancement using dual-band phase offset lines. In the proposed architecture, 50-dual-band offset lines with arbitrary electric lengths at two frequencies are key components, and a novel analytical design solution has been proposed for their design and implementation. The methodology is validated with the design and fabrication of a 10-W GaN-based DPA for code division multiple access and… CONTINUE READING
