E-Band Faraday Isolator Copyright © 2021 by Eravant Description: Model STF-12-S1 is a full band Faraday isolator that operates from 60 to 90 GHz. The Faraday isolator is constructed with a longitudinal, magnetized ferrite rod that causes a Faraday rotation of the incoming RF signal. The isolator offers 1.5 dB typical insertion loss and 28 dB nominal isolation with good flatness. The return loss of the isolator is 16 dB. The input and output ports are WR-12 waveguides with UG-387/U anti-cocking flanges. Features:
- Full Waveguide Band Operation
- Moderate Insertion Loss
- High Isolation
- Instrumentation Grade Applications:
- Test Labs
- Instrumentations
- Sub-assemblies Electrical Specifications: Parameter Minimum Typical Maximum RF Frequency 60 GHz 90 GHz Insertion Loss 1.5 dB 2.0 dB Isolation 28 dB Return Loss 16 dB Power Handling 1.0 W (CW) 1.2 W (CW) Specification Temperature +25 °C Operation Temperature -40 °C +85 °C Mechanical Specifications: Item Specification RF Input and Output WR-12 Waveguide with UG-387/U Anti-Cocking Flange Waveguide Flange Material Brass Waveguide Flange Finish Gold Plated Cover Material Aluminum Cover Finish Black Anodized Weight 2.45 Oz Insertion Length 2.5” Outline TF-SE-A
