Abstract

A power amplifier is an electronic circuit that increases the power of a signal. For 5G sub-6GHz applications, this project describes a detailed analysis, design, and simulation approach for PA at 3.5 GHz. Higher frequency communications are typically more prone to interference than lower frequency ones. Because it is a lower frequency band than 6 GHz, the 2.4 GHz frequency band can be more prone to interference. The objective of this project is to design and simulate a microwave amplifier for a 5G sub-6 GHz application specifically on 3.5 GHz. This project is comparing the performance between Gallium-Nitride (GAN) High-Electron Mobility Transistor (HEMT), CG240025 and Gallium Arsenide (GaAs) Pseudomorphic High- Electron Mobility Transistor (pHEMT), AM030WX-BI-R to design the matching network and DC biasing network by using Advanced Design System (ADS) software. Hence, AM030WX-BI-R has a better performance because of the high gain (17.799 dB) and a low noise figure (1.223 dB). To conclude, power amplifier projects in 5G are essential to improving healthcare accessible, enhancing well-being, and supporting programs aimed at strengthening people's health and safety because they enable dependable, high-speed communication
