Design Equations for Class-E Power Amplifiers [PDF]
, 2006 In literature, it is widely accepted that the design of Class-E Power Amplifier (PA) with finite dc feed inductance requires a long iterative solution procedure. To avoid such iterative solution methods, analytical design equations should be known.

1 kW MHz Wideband Class E Power Amplifier
IEEE Open Journal of Power Electronics, 2022 Class E power amplifiers are widely used in high-frequency applications due to their simplicity and use of only one ground-referenced switch. However, Class E power amplifiers are usually tuned to operate at a fixed frequency due to their resonant nature.

Microwave class-E power amplifiers [PDF]
2017 IEEE MTT-S International Microwave Symposium (IMS), 2017 This paper reviews circuit architectures and demonstrated class-E power amplifiers in the UHF and microwave frequency range. Scaling class-E soft-switching operation to high frequencies presents a number of challenges, particularly in the control of parasitic reactances of the device and the circuit.

High Efficiency Power Amplifier Based on Envelope Elimination and Restoration Technique [PDF]
, 2010 Due to complex envelope and phase modulation employed in modern transmitters it is necessary to use power amplifiers that have high linearity. Linear power amplifiers (classes A, B and AB) are commonly used, but they suffer from low efficiency especially
