This calculator determines the turns ratio between the primary and secondary windings of an RF transformer based on their impedances. It helps design impedance-matching networks for efficient signal transfer in RF circuits.
Formulas
Primary to Secondary Ratio: Np / Ns = √(Zp / Zs)
Secondary to Primary Ratio: Ns / Np = √(Zs / Zp)
Formula Explanation
- Zp = Primary winding impedance (Ω)
 - Zs = Secondary winding impedance (Ω)
 - Ratios are dimensionless and used to design matching networks.
 
Example
Input: Zp = 50 Ω, Zs = 200 Ω
Result: Np/Ns = 0.5, Ns/Np = 2
Who uses it
Ideal for RF circuit designers and engineers working on impedance matching and signal transfer optimization in communication systems.
