Abstract
In this paper the millimeter-wave passive components developed for the Ka-band Bar-SPOrt (Balloon-borne Radiometer for Sky Polarization Observatory) correlation radiometer are described. Comparison between numerical and experimental results are reported for all the building blocks of the radiometer: marker injector, polarizer, ortho-mode transducer, filtering sections and correlation unit. Due to the very low level of the polarized sky emission to be measured, all the components were designed and manufactured in order to achieve a very high level of sensitivity.
