Description
The ESA Planck satellite is designed to achieve precision imaging of the
Cosmic Microwave Background with an unprecedented combination of angular
resolution, sensitivity, spectral range and sky coverage. The Low
Frequency Instrument is one of two complementary instruments, and covers
30, 44, and 70 GHz with an array of wideband pseudo-correlation,
cryogenic radiometers. Advanced qualification models of the radiometer
chains and of the instrument electronics have been manufactured, tested
and integrated into the LFI Qualification Model. The main radiometer
calibration, RF tuning and performance characterization is carried out
at a single radiometer chain level, and then verified at instrument
integrated level in dedicated cryofacilities. Here we describe the main
requirements and instrument design, and we summarize the radiometer
calibration strategy optimised during the qualification activity in view
of the LFI Flight Model campaign.
