HERRERA DEL CUETO, Leonardo. Design of a Class-E broadband power amplifier using filters topology for matching. EAC [online]. 2020, vol.41, n.2, pp. 18-29.  Epub 01-Ago-2020. ISSN 1815-5928.

This paper presents a method for designing a power amplifier for high efficiency Class-E broadband topology using a low-pass filter of a high order is presented. A study of the state of the art regarding the design of a power amplifier Class-E performed operating within the frequency band of 0.8 GHz to 1.5 GHz. In the design accordingly ensures the attenuation of the power of the second and third harmonic, critical to achieving high efficiency amplification criterion. The design equations and simulation were made in AWR Design Environment V13. The efficiency levels achieved were 74%, the efficiency of added power (PAE) 72% power gain was more than 8 dB across the band, a bandwidth of 665 MHz, and the band of 60.8% was achieved, with an efficiency drain and PAE above 50%.
