The polarizer offers a typical insertion loss of 0.5 dB, typical axial ratio of 1.2, and a typical return loss of 20 dB. The polarizer is fixed and can be used for either right-handed or left-handed polarization based on the direction of the input signal. The polarizer is often combined with Eravant’s rectangular to circular waveguide transition (SWT-08094-SB) and WR-08 conincal antenna (SAC-2309-094-S2) for various system applications.

- The polarizer’s product label indicates the direction of Left-Handed Circular Polarization (LHCP).
- An example configuration diagram is provided below. The diagram indicates the input and output ports and the orientation in which the polarizer is to be attached to the rest of the components to obtain an LHCP signal at the output port.
- The polarizer can be configured to obtain a Right-Handed Circular Polarized (RHCP) signal at the output port by reversing the input and output ports as shown in the second diagram.
