## Abstract The design of broadband matching networks (MNs) exploiting filter theory is presented in this article for synthesizing broadband and highly efficient power amplifiers (PAs).Starting from sets of optimum impedances over the design frequency (obtained from load/pull measurement), the MNs

Abstract
Optimum choice of bias point, load and drive level for solidβstate power amplifiers is performed via a design methodology based on a novel iterative analysis method. The effectiveness of the proposed methodology and the corresponding level of accuracy is demonstrated through a comparison with the results of a more elaborate commercial CAD software and with experimental data, Β© 1994 John Wiley & Sons, Inc.

## Abstract In this study, a special inverted Doherty topology and uneven power drive methods are proposed to optimize the efficiency and appropriate load modulation. The amplifier is optimized at large power backβoff. The power added efficiency and adjacent channel leakage ratio (ACLR) are 33.1% a
The new analytical method presented in this paper extends the principle of the equivalent small parameter method (ESP, an improved perturbation technique) to analyse and design Class E power ampli"ers. Using this method the analytical expression for the output voltage (or current), containing the fu
