Stripline and Microstrip calculator (PRO ONLY)

• Matching ladder network circuit with serial/parallel capacitors, serial/parallel inductors, serial/parallel resistors

• 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.

• Impedance sweep over a range of frequencies. Frequency sweep resolution can be adjusted.
