Smith Chart Pro
Lightweight powerful professional Smith Chart RF Impedance Matching Tool..
Features:NEW FEATURES: Automatic Stub Matching, Transformer Matching Coming Soon: Stripline and Microstrip calculator• Matching ladder network circuit with serial/parallel capacitors, serial/parallel inductors, serial/parallel resistors, serial transmission line, open-circuit and short-circuit stub.• Add Q, Gain (GA, GP), VSWR, Stability (Source, Load) circles• S-parameter s2p file import capability.• This pro version enables up to 7 matching circuit elements.• User friendly with adjustable seek bars and edittext boxes to move element parameter and the resultant impedance value in the smith chart with high precision.• First starting data point can be entered using either normalized impedance or reflection coefficient. • System impedance and operating frequency can be adjusted.• Provides additional details such as VSWR, Q, Return loss, normalized admittance value and transmission line physical length at each impedance value.• Capable of undoing circuit element and retrieving previous states.• Transmission line, open-circuit and short-circuit stubs can be designed with different line impedance and effective relative permittivity. • Impedance sweep over a range of frequencies. Frequency sweep resolution can be adjusted.• Every impedance matching stage is clearly annotated with different colored line and number.Bug fixes

Sounds good, but interface is clumsy and display of values and chart extremely poor. Will try again when improved. Looking forward to much improvement and will re- purchase. I suggest separate page for editing circuit and smith chart - toggling between each. Ability to print a 2-page output would be great.
I am impressed but not overly excited!
Good 👌 my way to get my matching impedance circuits.
Interface is unfriendly and the chart is too small with poor use of colours making difficult to see.
good app rf matching
Great tool, thanks!
Works OK, but would be much more useful if you could go back and edit circuit elements after they are placed, ie interactive tuning
Please check the single series short/open circuited stub for Z=10+j20. I think the answers are incorrect
Easy and simple. Just the simple tool I was looking for.
App helps learning about the concepts behind Z matching.
