The hybrid is based on a cavity and two novel broadband coaxial-to-double ridged waveguide transitions. The design was optimized using a commercial 3-D electromagnetic simulator. The device was tested at room and cryogenic temperature. At the physical temperature of 77Kthe measured input reflection was less than -17 dB, the maximum deviation from the ideal -3dB coupling and 180° phase difference were respectively +/- 0.25 dB and +/- 0.9°. The experimental results are in good agreement with simulation.STAMPAenArticle10.1109/LMWC.2010.2089505https://ieeexplore.ieee.org/document/5659498FIS/05 - ASTRONOMIA E ASTROFISICAERC sectors::Physical Sciences and Engineering
