## Description

From the author of "Microwave Active Circuit Analysis and Design" : A free S-parameter design tool for RF and microwave engineers.

The S-Parameter Design Tool is an S-parameter analysis tool for RF and microwave engineers. Just enter your transistor's S-parameters, choose the device configuration and feedback termination (if any) and the app will compute stability factors, simultaneous conjugate match points, and maximum available gain — all displayed on an interactive Smith chart.

Features:
• S-parameter entry in magnitude/angle, real/imaginary, or dB/angle format
• Common-emitter, common-base, and common-collector configuration conversion
• Series and shunt feedback analysis
• Stability analysis: Rollett K-factor, µ1/µ2, stability circles
• Smith chart and polar plot display
• Results export as CSV

This is a companion App to the website tool: https://www.clivepoole.com/s-parameter-design-tool/
All based on our Book: “Microwave Active Circuit Analysis and Design” by C. Poole and I Darwazeh, Elsevier 2015, ISBN 13: 9780124078239.
