Multiple choice general knowledge

Why should core saturation of a conventional impedance matching transformer be avoided?

  1. Harmonics and distortion could result

  2. Magnetic flux would increase with frequency

  3. RF susceptance would increase

  4. Temporary changes of the core permeability could result

A Correct answer
Explanation

Core saturation causes non-linear behavior in the transformer, introducing harmonics and signal distortion. When saturated, the core cannot properly respond to magnetic field changes, degrading signal quality.
