TL;DR: The Planck Low Frequency Instrument (LFI) as mentioned in this paper is an array of microwave radiometers based on state-of-the-art Indium Phosphide cryogenic HEMT amplifiers implemented in a differential system using blackbody loads as reference signals.

TL;DR: The QUIJOTE (Q-U-I JOint Tenerife) CMB Experiment will operate at the Teide Observatory with the aim of characterizing the polarisation of the CMB and other processes of Galactic and extragalactic emission in the frequency range of 10-40GHz and at large and medium angular scales as discussed by the authors.

TL;DR: The C-Band All-Sky Survey (CAS) as discussed by the authors is a project to map the full sky in total intensity and linear polarization at 5 GHz at the Owens Valley Radio Observatory in California, USA.

TL;DR: The 30 and 44 GHz Front End Modules (FEMs) for the Planck mission to be launched in 2009 are described in this paper, where a differential pseudo-correlation radiometer in which the signal from the sky is compared with a 4-K blackbody load is used.
