This calculator allows you to determine the transformation ratio of an RF transformer from the primary and secondary impedances. It helps match impedances between different parts of an RF circuit to maximize power transfer and reduce return losses.
Formulas
Np / Ns = √(Zp / Zs)
Ns / Np = √(Zs / Zp)
Explanation of formulas
The Np/Ns and Ns/Np ratios represent the number of turns of the primary in relation to the secondary and vice versa. Zp and Zs are the primary and secondary impedances in ohms. These relationships make it possible to match a source and a load with different impedances for maximum efficiency of the RF circuit.
Uses of the calculator
- Design of RF transformers for impedance matching.
- Optimization of power transfer between amplifier stages.
- Rapid analysis and verification of turns ratios in RF circuits.
- Useful for RF engineers, circuit designers and electronics students.
