Model STF-28-91 is a full band Faraday isolator that operates from 26.5 to 40 GHz. The Faraday isolator is constructed with a longitudinal, magnetized ferrite rod that causes a Faraday rotation of the incoming RF signal. The Faraday isolator offers 30 dB typical isolation and a 1.2 dB nominal insertion loss with good flatness. The return loss of the isolator is 14 dB. The input and output ports have WR-28 waveguides with UG-599/U flanges and feature a 90° twist.
