Description:Smith Charts is a professional RF design utility for plotting, analyzing, and matching impedances on an interactive Smith chart. Ideal for antenna tuning, microwave circuits, and lab workflows, it turns network analyzer data into clear insights. Core features include interactive plotting of S-parameters and impedance, one-tap matching network synthesis with series or shunt L and Pi or T options, and real-time readouts for VSWR, return loss, reflection coefficient, and Q. Boost productivity with drag markers, frequency sweeps, overlay traces, templates, and export of charts and data. Designed for engineers, students, and hobbyists seeking a fast, accurate impedance matching tool and RF calculator.
How to use:1. Download and open the app, then choose Create Project or open a sample chart.
2. Import data as Touchstone files (.s1p, .s2p) or enter impedance or admittance values manually.
3. Explore the plot by zooming and panning, drag markers, and move the frequency cursor to view VSWR, return loss, and reflection coefficient in real time.
4. Add matching networks by selecting series or shunt elements, set a target impedance or VSWR, and apply suggested L, Pi, or T solutions.
5. Compare and export by overlaying multiple traces, saving presets, and exporting images or CSV data for reports or collaboration.
