In the design, two different single Power Amplifiers (PAs) are combined using a Wilkinson power divider which is also used to connect the power to the load. The designed DPA operates in the range of 2.0-3.0 GHz and aims to achieve high efficiency, wide bandwidth and high output power for 5G applications. Simulation results showed a 40% fractional bandwidth and more than 44 dBm of saturated output power. In addition, the Power-Added Efficiency (PAE) and Drain-efficiency (Deff) are about 77% and 84%, respectively. A comparison with the other previous works shows enhancement in the maximum large-signal gain (L_S_Gain) in the average of 2.5 dB and an average PAE of about 10%. This improvement can be attributed to the deployment of the power divider\/combiner proposed in the design and also the optimization of the components during the design.<\/jats:p>","DOI":"10.12720\/jcm.17.8.675-681","type":"journal-article","created":{"date-parts":[[2022,10,8]],"date-time":"2022-10-08T09:41:06Z","timestamp":1665222066000},"page":"675-681","source":"Crossref","is-referenced-by-count":9,"title":["Design of a High-Efficiency Doherty Power Amplifier for 5G Applications Using Wilkinson Power Divider"],"prefix":"10.12720","author":[{"name":"Department of Electrical Engineering, Pan African University, Institute for Basic Sciences Technology and Innovation, PAUSTI, Nairobi-6200-00200, Kenya","sequence":"first","affiliation":[]},{"given":"Issoufou G.
