Abstract

This paper presents a design and analysis of the class B power amplifier for all digital applications. The enlightened power amplifier is designed at 868 MHz for an application such as Low-Power Wide Area Network (LPWAN). Analysis of the power amplifier for the digital RF pulsed power in comparison of simple RF power has been addressed in term of Power Aided Efficiency (PAE) and gain. Characterized power amplifier offers a return loss of ˜26dB, a large signal gain of ˜18.5dB, a PAE of ˜ 47%, and Error Vector Magnitude (EVM) for (Long-Term Evolution) LTE modulated signal with ˜2.5%.
