Foundations of Passive Microwave Circuits and Measurements

Understanding how high-frequency signals behave is essential for modern wireless communication, radar systems, and high-speed electronics. This course demystifies the fundamental physics and engineering principles behind passive microwave circuits without requiring advanced prior knowledge. You will transition from basic circuit theory to high-frequency electromagnetics, gaining the confidence to analyze transmission lines, design key passive components, and understand standard laboratory measurement procedures. What you'll learn: 1. Learn the foundational principles of transmission line theory, wave propagation, and S-parameters. 2. Design and analyze essential passive devices including power dividers, couplers, and filters. 3. Understand the operation of waveguides, microstrips, and stripline configurations for modern high-frequency boards. 4. Master the basics of impedance matching using Smith charts and analytical techniques. 5. Explore practical measurement methodologies using Vector Network Analyzers (VNAs) and calibration standards. 6. Apply modern design workflows for high-speed PCB layouts and electromagnetic simulation preparation. We begin with essential terminology, electromagnetic wave basics, and transmission line models. From there, you will explore practical component design and study the measurement techniques used in modern laboratories to verify high-frequency performance. This text-based course is designed for engineering students, hobbyists, and entry-level hardware developers who want to build a solid foundation in microwave engineering.
