Abstract
An amplifier output impedance matching configuration including a first impedance transformer and one or more second impedance transformers. The first impedance transformer receives input signals from a power amplifier and generates output signals to a load. The one or more second impedance transformers are connected between the first impedance transformer and the load through which the output signals are passed.
