Design and Simulation of Class-E Powe Amplifier having Single Stage and 2-Stage at 2.4 GHz for IOT

Abstract

In this project, we have designed a single-stage & 2-stage power amplifiers operated on 2.4 GHz. The purpose of this design is to provide better efficiency and high gain. This can be done by improving impedance matching techniques & by using harmonic suppression. In these two stages of power amplifiers, it consists of two inductors and two capacitors which are used to build harmonic suppression circuits. The basic purpose of these components is to increase the overall of efficiency of power amplifiers. In these circuits of power amplifier, VCC of 4.2 v is given and input & output impedances are matched to 50 ohms. In our project, we have simulated single and 2-stage amplifiers on ADS. We have observed the gain and power added efficiency for single stage power amplifier which are 16.932 dB and 45.496% respectively. While for the Two stage amplifier, the gain and power added efficiency are 28.625 dB and 42.285% respectively.
