@conference{10902/3268, year = {2012}, month = {9}, url = {http://hdl.handle.net/10902/3268}, abstract = {This document describes the scheme and prototype test results of a broadband radioastronomy receiver aimed to obtain polarisation data of Cosmic Microwave Background (CMB) radiation from the sky. Nominal receiver bandwidth is 26 to 36 GHz. The radiometer will work as a polarimeter to obtain the polarisation Stokes parameters (Q, U and I) of the incoming electromagnetic signal to the feed-horns. Prototype tests have demonstrated the receiver concept based on electronic phase switching in two balanced branches. The correlation between signals is performed directly at 31 GHz by a broadband 3 dB/180º hybrid coupler.}, publisher = {URSI 2012, XXVII Simposium Nacional de la Unión Científica Internacional de Radio, Elche}, title = {Receptor de polarización a 31 GHz para radioastronomía}, author = {Artal Latorre, Eduardo and Aja Abelán, Beatriz and Cagigas Ibañez, Jaime and Cano de Diego, Juan Luis and Fuente Rodríguez, Luisa María de la and Mediavilla Sánchez, Ángel and Terán Collantes, José Vicente and Villa Benito, Enrique and Hoyland, Roger J. and Casas Reinares, Francisco Javier and Ortiz García, David}, }
