SAS-793-11012-F1

Rev 1.1

Description:
Model SAS-793-11012-F1 is an E band, linear tocircular polarizer that operates from 71 to 86 GHz.
The polarizer offers a typical insertion loss of 0.5
dB, a typical axial ratio of 1.1, and a typical returnloss of 20 dB. The polarizer is fixed and can beused 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 waveguidetransition (SWT-12110-SB) and WR-12 conical horn antenna (SAC-2309-110-S2) for various systemapplications.

Note:• All data presented is collected from a sample lot. Actual data may vary unit to unit, slightly.
• All testing was performed under +25 °C case temperature• The Polarizer is offered as LHCP. However, it can be used as RHCP by reversing the input andoutput ports.
• Eravant reserves the right to change the information presented without notice.
Caution:• Any foreign objects in the polarizer will cause performance degradation and possible device
damage.

LHCP and RHCP Polarization Configuration Notes and Diagram:•••

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 andoutput ports and the orientation in which the polarizer is to be attached to the rest of thecomponents to obtain a LHCP signal at the output port.
The polarizer can be configured to obtain a Right-Handed Circular Polarized (RHCP) signal at theoutput port by reversing the input and output ports as shown in the second diagram.
