@conference{10902/5457, year = {2014}, month = {9}, url = {http://hdl.handle.net/10902/5457}, abstract = {This contribution presents the design and characterization of a WR22 waveguide correlation and detection module for polarimetry applications in radioastronomy covering the frequency band 35-47 GHz (30%). The module includes the design of a 3-dB 90º hybrid coupler, a 90º phase shifter, a waveguide termination and a Schottky diode detector. The 3-dB 90º hybrid coupler, tested separately, shows an input matching better than 20 dB and accurate phase and amplitude balances. The module itself provides the I, Q and U Stokes parameters simultaneously with good isolation and leakage values. Differences between expected and actual values are found to be due to mechanical tolerances.}, organization = {Los autores agradecen al Ministerio de Economía y Competitividad la financiación para la realización de estos trabajos a través del programa CONSOLIDER-INGENIO 2010 de referencia CSD2010-00064.}, publisher = {URSI 2014, XXIX Simposium Nacional de la Unión Científica Internacional de Radio, Valencia}, title = {Módulo de correlación y detección de banda ancha y banda Q en guía de onda}, author = {Pérez Quintanilla, Ana Rosa and Cano de Diego, Juan Luis and Villa Benito, Enrique and Mediavilla Sánchez, Ángel and Artal Latorre, Eduardo}, }
