SAS-19-219-M1 is a U band, linear to circular manual switchable polarizer that operates from 40 GHz to 60 GHz. The polarizer features a 5-position manual lever for switching between output polarization modes such as linear to left or right hand circular polarization depending on the input signal and linear to linear signals. The polarizer offers a typical insertion loss of 0.6 dB, typical axial ratio of 1.2, and a typical return loss of 20 dB. The polarizer is often combined with Eravant’s rectangular to circular waveguide transition (SWT-19219-SB) and (SAC-2309-219-S2) for various system applications.
