In this comprehensive tutorial, learn how to design a Low Noise Amplifier (LNA) using Advanced Design System (ADS). We’ll cover all essential steps including biasing, stability analysis, optimization, noise circle analysis, and circuit matching. From creating the workspace to simulating the full amplifier circuit, this guide takes you through the process step-by-step. 🎛️📐
We use the HP-AT41411 BJT transistor, known for its low noise and high frequency performance, making it ideal for RF applications like LNA design.
