This work presents an experimental investigation of class E power amplifier with parallel shunt network along with two similar amplifier obtained by adding series-connected parallel resonant tanks tuned for the second (class E/F3) and the third harmonics with duty ratio of D=0.33. The aim was obtaining of decreasing of maximum drain-source voltage together with high efficiency remaining. The experimental results shown about 0.6 W output power with 80% efficiency and reducing of drain-source voltage up to 2.5 times of voltage supply.

Abstract
This work presents an experimental investigation of class E power amplifier with parallel shunt network along with two similar amplifier obtained by adding series-connected parallel resonant tanks tuned for the second (class E/F3) and the third harmonics with duty ratio of D=0.33. The aim was obtaining of decreasing of maximum drain-source voltage together with high efficiency remaining. The experimental results shown about 0.6 W output power with 80% efficiency and reducing of drain-source voltage up to 2.5 times of voltage supply.| File | Dimensione | Formato | |
