An asymmetrical spurline filter (ASF) with dual-bandgap characteristics is designed and applied as the load network of the class-E power amplifier to improve the output power and efficiency. Meanwhile, an equivalent circuit model is built for the proposed ASF based on two LCR resonators. V

## Abstract In this article, a new highly efficient and highly stable 1 kW power amplifier is designed and fabricated for plasma processing applications.The efficiency of the generator was improved by using a classβE type power amplifier consisting of one pushβpull MOSFET and a highβcurrent driver
## Abstract A balanced classβE power amplifier (PA) using a pushβpull GaN HEMT for high power and high efficiency is represented. For validation, a classβE PA is designed and implemented using a pushβpull type GaN HEMT and tested for a single tone of 2.14 GHz. The measured results show that the bal
## Abstract We have designed and realized a highly linear power amplifier module (PAM) for a WiMAX/WiBro base station using a simple linearization method. To improve the linearity of the PAM, we use largeβsignal intermodulation distortion (IMD) sweet spots, which are part of the inherent properties
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
