Amplificador distribuido 0-28GHz para aplicaciones ópticas

This contribution presents a MMIC cascade distributed amplifier (CDA) in 0.15 μm low noise pHEMT process for optical transmission system. The device covers from DC to 28 GHz, achives a small signal gain of around 17 dB, input and output return losses are better than 15.7 dB and 14.15 dB, respectively, and has a maximum noise figure of 6.5dB. The distributed amplifier (DA) consumes 178 mA from 8 V supply, and its dimensions are: 3.07x1.82 mm2
