Amplitude Balance

A measure of the absolute difference in signal amplitude between each output of a center-tapped transformer relative to the center-tap.

Phase Balance

A measure of the difference in signal phase between each output of a center-tapped transformer relative to the center-tap.

Insertion Loss

The amount of power lost through the transformer under matched conditions.

Balun

A transformer that has a balanced input, where both ports are isolated from ground, to an unbalanced output where one side is connected to ground.

Autotransformer

A transformer where the secondary winding also comprises a portion of the primary winding.

1 dB Bandwidth

The frequency range over which insertion loss is less than 1dB referenced to the midband insertion loss.
