Microwave Circuit Design: A Practical Approach Using ADS
is a comprehensive guide by author Kyung-Whan Yeom, designed to bridge the gap between theoretical microwave engineering and industry-standard design practices. The book primarily focuses on active microwave circuit design, a field that has seen explosive growth due to the expansion of mobile and satellite communication systems. Core Concepts and Philosophy
To design a microwave circuit using ADS, follow these steps:
- Plan on paper (use a Smith Chart PDF).
- Simulate schematics with variables.
- Optimize using goals and optimizers.
- Validate with Momentum EM simulation.
- Document using ADS’s built-in report generation (export to PDF).
. "Stop fighting the math by hand," she said. "Use the physical interpretation. Let the simulator show you where the energy is actually going." Bridging the Gap microwave circuit design a practical approach using ads pdf
The electromagnetic behavior of the circuit is analyzed using ADS Momentum, as shown in Figure 5.
For professors designing coursework, the book serves as a structured roadmap for transforming students into engineers. It answers the pervasive student question: "Why does my simulation not match the theory?" By guiding readers through layout effects, grounding issues, and packaging parasitics within ADS, the text fosters a deeper intuition for microwave behavior that purely mathematical approaches often fail to convey.

Momentum
| Mistake | Practical ADS Solution | | :--- | :--- | | Ignoring parasitic capacitance | Run on the critical net. | | Using ideal grounds | Replace all grounded components with a Via model from the library. | | Simulating at one temperature | Use Parameter Sweep for -40°C, 25°C, 85°C. | | No EM co-simulation | Use EM-Circuit Co-simulation to treat critical traces as EM components and the rest as schematic. |
Active Devices & Parameters:
Introduction to microwave semiconductor materials (FET, BJT), DC biasing, and the use of S-parameters and noise parameters for high-frequency characterization. Plan on paper (use a Smith Chart PDF)
Kyung-Whan Yeom’s "Microwave Circuit Design: A Practical Approach Using ADS" bridges electromagnetic theory and modern engineering by using Keysight's ADS software for hands-on, practical simulation. It covers foundational concepts like S-parameters and transmission lines, alongside core active component design for LNAs, PAs, and mixers. For more details, visit Amazon .
