@conference{10902/11126, year = {2016}, url = {http://hdl.handle.net/10902/11126}, abstract = {We present low-noise amplifiers (LNA) that have been developed in the framework of two pre-qualification ESA projects for frequencies between 54 and 229 GHz for the METOP-SG satellite program. The main goal of these satellites is water vapor detection in atmospheric science and weather forecasting which advances the current state of the art for the metamorphic high electron mobility transistor (mHEMT) technology. The MMIC amplifiers are based on the In0.52Al0.48As/In0.8Ga0.2As/In0.53Ga0.47As heterostructure and utilize transistors with a gate length of 50 nm. On-wafer measurements will be presented for all frequency bands as well as results of packaged LNAs.}, publisher = {IEEE}, publisher = {Global Symposium on Millimeter Waves (GSMM) & ESA Workshop on Millimetre-Wave Technology and Applications, Espoo, Finland, 2016, 190-193}, title = {Low noise amplifiers for MetOp-SG}, author = {Rösch, Markus and Tessmann, Axel and Leuther, Arnulf and Weber, Rainer and Moschetti, Giuseppe and Aja Abelán, Beatriz and Kotiranta, Mikko and Massler, Hermann and Kangas, Ville and Perichaud, Marie-Genevieve and Schlechtweg, Michael and Ambacher, Oliver}, }
