STF-10-S1-C

Rev. 1.0

Description:
Model STF-10-S1-C is a full W band Faraday isolator that
operates from 75 to 110 GHz. The Faraday isolator isconstructed with a longitudinal, magnetized ferrite rod thatcauses a Faraday rotation of the incoming RF signal. The
compact, robust package is ideal for system integration andtesting applications. The Faraday isolator offers 28 dB typicalisolation and 1.5 dB nominal insertion loss with good flatness.
The input and output ports are WR-10 waveguides with UG387/U-M flanges. A 90° twist configuration is available under model number STF-10-91-C.
