Apparatus for transforming two elliptically polarized waves into two oppositely rotating circularly polarized waves. The two elliptically polarized waves are first transformed by a phase-shifter into two other oppositely rotating elliptically polarized waves having parallel major and minor axes and equal axial ratios. Attenuation equal to the reciprocal of the axial ratio is then applied to both the transformed elliptical waves thereby simultaneously converting the oppositely rotating elliptical waves into two oppositely rotating circular waves.
