Equivalent circuit of a wideband transformer:
- n - turn ratio of the transformer
- R1 - resistance of the primary winding
- R2 - resistance of the secondary winding referred to the primary side
- Rc - resistance representing the core loss
- Lleak1 - leakage inductance of the primary winding
- Lleak2 - leakage inductance of the secondary winding referred to the primary side
- C'1-1 - distributed capacitance of the primary winding represented as a lumped capacitance
- C'2-2 - distributed capacitance of the secondary winding represented as a lumped capacitance
- C'1-2 - distributed interwinding capacitance (primary to secondary winding)
