Two-stage amplification using intermediate non-linear square wave

Image Number 3 for United States Patent #7560985.

A two-stage amplifier is provided, which in the first stage, a first amplifier generates a non-linear square wave based on a harmonic input. The non-linear square wave has the same frequency as the harmonic input and is provided as an input to the second stage, in which a second amplifier generates an amplified harmonic output. The first amplifier and/or second amplifier can comprise a group-III nitride-based Heterostructure Field Effect Transistor (HFET). Additionally, the first amplifier can comprise a multi-harmonic Class F amplifier and the second amplifier can comprise a Class E amplifier.
