Analytical Design Equations for Class-E Power Amplifiers [PDF]
IEEE Transactions on Circuits and Systems I: Regular Papers, 2007 This paper presents the analytical solution in time domain for the ideal single-ended Class-E Power Amplifier (PA). Based on the analytical solution a coherent non-iterative procedure for choosing the circuit parameters is presented for Class- E PA’s with arbitrary duty-cycle and finite dc-feed inductance (e.g.

A novel inverse class E power amplifier topology
2013 21st Signal Processing and Communications Applications Conference (SIU), 2013 In this work, a 10 Watt inverse class-E power amplifier has been proposed, simulated, realized and measured for the 2.7-2.9 GHz wireless applications. In the proposed power amplifier topology distributed elements were used instead of lumped elements and their widths and lengths were optimized with AWR Microwave Office.
