High Performances Corrugated Feed Horns for Space Applications at Millimetre Wavelengths
F. Villa, M. Sandri, N. Mandolesi +11
We report on the design, fabrication and testing of a set of high performance corrugated feed horns at 30 GHz, 70 GHz and 100 GHz, built as advanced prototypes for the Low Frequenc…
The PLANCK LFI flight model ortho-mode transducers
O. D'Arcangelo, A. Simonetto, L. Figini +10
The Low Frequency Instrument (LFI) of the ESA Planck CMB mission is an array of 22 ultra sensitive pseudocorrelation radiometers working at 30, 44, and 70 GHz. LFI has been calibra…
