Electronic Products Design & Test magazine recently published an article titled, The Role of Isolators in mmWave Power Amplifiers, which discussed Micro Harmonics' new line of Faraday rotation isolators. “With exceptionally low insertion loss, the lowest by far of any isolator on the commercial market, the MHC D-band isolators have an insertion loss of less than 0.9 dB, which means it passes more than 82% [...]

Everything RF has published a detailed story about our Faraday rotation attenuators. The article discusses the challenges engineers are facing when trying to reduce the strength or magnitude of a radio frequency at frequencies above 50 GHz. The two most common electronically tunable variable attenuator technologies, PIN diode and resistive vane attenuators, both come with substantial drawbacks. Read the full article about our MMW variable [...]

By generating a 301.442 GHz wave, researchers were able to talk to nitrous oxide (N2O) molecules in a vacuum chamber. However, reflected waves interfered with the signal, delivering sub-optimal results. The researchers turned to Micro Harmonics for an isolator that operates within the WR 3.4 band (220GHz - 325GHz) and... “We plugged it in and got fantastic results,” explains James Greenberg in a recent article [...]

Time to redefine a second? While the cesium atom remains the industry standard for measuring time, the world’s first atomic clocks used a molecule (ammonia) instead of atoms. Now, researchers are returning to molecules to produce portable atomic clocks. Read about how our isolators are enabling this breakthrough at frequencies above 300 GHz. The full story was published in Microwave Product Digest.

Our new hybrid circulator has been granted a patent (No. 12,034,196). The new wideband hybrid circulator technology is a replacement for the traditional Y-junction circulator. The hybrid circulator is a passive device similar in size to the Y-junction but having an astounding 24% fractional bandwidth in every band from WR-15 (54-68 GHz) through WR-3.4 (258-330 GHz).

Micro Harmonics is pleased to announce that we have once again been placed on the Inc. 5000 List of Fastest-Growing Private Companies. Read our press release here.

We were featured in this month’s issue of Microwave Journal! The story is about a common issue in MMW systems, out-of-phase reflected signals which can perturb the operating point of the upstream component. Read about how our isolators are solving this issue all the way into the THz regime.

Design Engineer, James Greenberg was quoted in a recent story that appeared in Electronics for Engineers saying, “The Micro Harmonics isolators have a really wide band which allows us to look at a range of molecules at different frequencies using the same spectrometer as previous experiment with the exact same isolator.” Read the full story here.

System designers are overcoming the issue of signal reflections at MMW and THz frequencies. “High isolation was extremely important, and we were getting 30 dB of isolation with the isolators from Micro Harmonics at over 300 GHz,” explains Research Scientist James Greenberg.
