The authors outline the main features of the COBRAS/SAMBA Low Frequency Instrument (LFI), which is designed to image the CMB anisotropies in the frequency range 30 - 130 GHz. The instrument is based on an array of corrugated feed horns coupled with passively cooled, low-noise HEMT receivers employing microwave integrated circuits technology. The authors describe the receiver concept and present simulations of the in-flight instrument calibration using the CMB dipole signal.

Abstract
The authors outline the main features of the COBRAS/SAMBA Low Frequency Instrument (LFI), which is designed to image the CMB anisotropies in the frequency range 30 - 130 GHz. The instrument is based on an array of corrugated feed horns coupled with passively cooled, low-noise HEMT receivers employing microwave integrated circuits technology. The authors describe the receiver concept and present simulations of the in-flight instrument calibration using the CMB dipole signal.File in questo prodotto:
