Using Baluns and RF Components for Impedance Matching
and the balun has a 1 : 1 impedance ratio. When the load impedance is mismatched to the source in a 1 : N imped-ance ratio, a 1 : N impedance ratio transformer is required. A classic example of an impedance mismatched circuit is a 300 Ohm ribbon cable (balanced) from an antenna
