Abstract:MHEMT devices with 60% indium channels gave transport characteristics similar to An excellent 0.61 dB minimum noise figure and 11.8 dB associated gain at 26 GHz, have been obtained for a InP-based HEMTs with room-temperature sheet InAlAsAnGaAs metamorphic HEMT on a GaAs densities and mobilities of 3 . 2~1 0 '~ cm-2 and substrate. 10,500 cm2N.s. Atomic force microscopy Low-noise amplifiers show under 1.8 dB noise figure showed an RMS surface roughness of 11 W. The with gain greater than 24 dB across 27 -32 GHz.… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
