The HMID12-387-73.5-5.0 from HXI is double ferrite junction isolator that operates from 81 to 86 GHz. It has an insertion loss of 0.8 dB, an isolation of 40 dB, and can handle up to 2 W of input power. The isolator is available in a module with WR-12 waveguide at the output with a standard UG–387/U flange. It can be used for buffer mismatches in high VSWR components and at the output of amplifiers and oscillators. It can also be used at the input to detectors in measurement applications.
