Micro Harmonics introduces a new WR-10 cryogenic isolator (75-110 GHz). Typical insertion loss is less than 0.4 dB at 77 K. Typical isolation is greater than 26 dB at 77 K. Nominal insertion loss and isolation are maintained at room temperature at 1.0 dB and 19 dB respectively. Prototypes have been rigorously tested through more [...]

Micro Harmonics has been awarded a new NASA SBIR contract for the development of millimeter-wave isolators optimized for cryogenic applications. The initial development will be done in WR-10 (75-110 GHz) with the ultimate goal to expand our product line to include cryogenic options in all bands from WR-12 (60-90 GHz) to WR-3.4 (220-325 GHz).

We have successfully demonstrated a WR-4.3 isolator covering the full waveguide band from 170-260 GHz with a typical insertion loss near 2 dB. New Micro Harmonics MMW Isolators For Applications Requiring Superior Isolation And Low Insertion Loss »   In addition to this news, we gave a live demonstration of our WR-3.4 isolator at the [...]

Micro Harmonics completes NASA Phase II development for MMW isolators and circulators.
