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.       Recently Added Patents Cooled ablation catheter with reciprocating flow Inductive power outlet locator No touch synthetic full backup 3-(4-((1H-imidazol-1-yl)methyl)phenyl)-5-aryl-1,2,4-oxadiazole derivatives as sphingosine-1 phosphate receptors modulators Method of manufacturing laminated body Cooling apparatus for internal combustion engine, method of controlling the same, and hybrid vehicle including the same Methods and arrangements in a wireless communications system   Randomly Featured Patents Recess gate transistor structure for use in semiconductor device and method thereof Process for oxidizing thallium (I) to thallium (III) Organopolysiloxane composition for elastomer foam Nonvolatile semiconductor memory device with a multi-layer sidewall spacer structure and method for manufacturing the same Facsimile transceiver Multilevel security apparatus and method Adjustable support Conformable optical couplers Information system Rotary gerotor hydraulic device with fluid control passageways through the rotor © 2006-2008 PatentGenius.
