RF Transformer Calculator

This page provides information about RF transformer calculators and their applications. The most common core used for RF transformers is the toroid.

A toroid is a circular, doughnut-shaped core usually made of a special type of powdered iron material. To create an RF transformer, copper wire is wound on the toroid to create both primary and secondary windings.

EXAMPLE:

• Input impedance = 5 Ω
• Output impedance = 50 Ω
• Ratio of Np to Ns = 0.316

Hence, Primary turns are 3.16 times more than the Secondary turns.
