In this paper we present the Low Frequency Instrument (LFI), designed and developed as
part of the Planck space mission, the ESA programme dedicated to precision imaging of the …

This paper provides an overview of the Low Frequency Instrument (LFI) programme within
the ESA Planck mission. The LFI instrument has been developed to produce high precision …

Abstract The Low Frequency Instrument (LFI) is an array of pseudo-correlation radiometers
on board the Planck satellite, the ESA mission dedicated to precision measurements of the …

This paper presents and discusses the careful modeling of a Zero Biased Diode, including
low-frequency noise sources, providing a global model compatible with both wire bonding …

Abstract The Planck Low Frequency Instrument (LFI) radiometers have been tested
extensively during several dedicated campaigns. The present paper reports the principal …

This paper presents and discusses three different low-cost microstrip implementations of
Schottky-diode detectors in W Band, based on the use of the Zero Bias Diode (ZBD) from …

The Low Frequency Instrument (LFI) on-board the ESA Planck satellite carries eleven
radiometer subsystems, called radiometer chain assemblies (RCAs), each composed of a …

We give a description of the design, construction and testing of the 30 and 44 GHz Front End
Modules (FEMs) for the Low Frequency Instrument (LFI) of the Planck mission to be …

In this paper we discuss the linearity response of the Planck-LFI receivers, with particular
reference to signal compression measured on the 30 and 44 GHz channels. In the article we …

This paper describes the Planck Low Frequency Instrument tuning activities performed
through the ground test campaigns, from Unit to Satellite Levels. Tuning is key to achieve the …
