A concurrent 5.5/12.5-GHz dual-band power amplifier (PA) is designed and implemented in a 0.25 ?m GaAs pseudomorphic high electron mobility transistor process. The PA composed of two stages adopts LC parallel series networks for matching. efficiency the improved by lowering drain voltage driver stage. Measurement results show that proposed features maximum small-signal gain 17.1 15.6 dB, output...

The study of products copper alloys the Lomatov culture X-XI centuries from collection Cherdyn Museum revealed two types patina. first pseudomorphic might be composed intergrowths chlorides formed upon interaction with sweat hands, or a zonal rim cuprite-malachite-azurite composition, due to groundwater. second type, which distorts shape original product, is associated leaching and other metals...
