*Insertion Loss: As much as 20% of the amplifier's power is wasted through the transformers. This figure should be accounted for and compared to when calculating the losses encountered through various sizes of low impedance wiring. | *Insertion Loss: As much as 20% of the amplifier's power is wasted through the transformers.

*Capacitance: To handle higher powers, transformers have to be scaled up in size. The added capacitance begins to attenuate high frequencies. | *Capacitance: To handle higher powers, transformers have to be scaled up in size. The added capacitance begins to attenuate high frequencies. | ||
