• Add Q, Gain (GA, GP), VSWR, Stability (Source, Load) circles
• S-parameter s2p file import capability.
• Free version enables up to 2 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.
• Every impedance matching stage is clearly annotated with different colored line and number.
• Serial transmission line, open-circuit and short-circuit stub matching elements.
• Transmission line, open-circuit and short-circuit stubs can be designed with different line impedance and effective relative permittivity. Line physical length is provided as well.

by Q####:

Buggy, if you set the same parameters several times you got different results and if you have a VNA to verify this you'd be surprise that the result of this app is not the same or even likely.

Doesn't let you open the it before rating. So i don't know yet.

Excellent and handy. Constant SWR circles in color will improve.
