Módulo posterior para la integración de polarímetros multi-pixel a 40 GHZ en radioastronomía

Abstract

This work presents the design and future integration of the back-end module for the 40 GHz instrument of the QUIJOTE project, which is a project aimed to the measurement of the Cosmic Microwave Background’s polarization. This contribution focuses on the importance of the concept of modularity in order to facilitate the integration tasks and to enable the assembly of a high number of receivers (pixels) in the instrument, which improves the overall sensitivity. Performance measurements of each individual subsystem are provided and the foreseen whole integration in a metallic rack is presented.
