Millitech’s high performance E-Band Linear-to-Circular Polarizer offers a low axial ratio of < 0.6 dB, a low insertion loss of < 0.5 dB, and a typical VSWR of 1.25:1 within the high and low unlicensed communication bands (71 – 86 GHz).

This polarizer can be optimized for any frequency you require from 18 – 110 GHz and above.

This polarizer covers nearly 2X the bandwidth and has 0.4 dB better axial ratio. We specify maximum insertion loss of 0.6 dB and Industry leading axial ratio performance.

This best-in-class polarizer is 1-inch long and can easily be integrated with Millitech’s other products that use 0.125 inch circular waveguide, including our Orthomode Transducer (OMT), Scalar Horn (SFH), and Millitech’s Cassegrain Reflector Antenna (CRA) or Gaussian Optics Lens Antenna (GOA).
