4. Results and DiscussionThe basic sub-circuit of the designed concurrent dual-band Doherty power amplifier is realized, and all the circuit units are combined into the final circuit. The topology of the overall circuit consists of a broadband Wilkinson power divider, a carrier power amplifier, a peak power amplifier, and an impedance converter, as shown in Figure 12. To further validate the proposed design, physical fabrication and testing were carried out. The fabricated DPA is shown in Figure 13.
