Micro Harmonics Corporation announces changes to the leadership team. This new chapter for MHC represents an exciting blend of continuity and growth. Together, we will continue to deliver exceptional millimeter wave component designs and drive the mission forward under our new leadership team. Read the press release here.
Microwave Product Digest published a story about the challenges of using isolators in MMW amplifiers. The article discusses how Micro Harmonics isolators are overcoming the notable drawback of conventional isolators. Among those mentioned in the article is the issue of insertion loss. Traditional isolators operating in the D-band (WR-6.5, 110-170 GHz) can have insertion losses [...]
Our new Faraday rotation-based attenuators are particularly well-suited for applications in telecommunications, radar systems, and test and measurement equipment operating at mm-wave frequencies. Their combination of high dynamic range, low insertion loss, and compact size makes them ideal for field use in aerospace and defense systems, where both performance and portability are critical.

Our new Faraday rotation attenuators were just featured in an article published in Design2Part magazine. These attenuators utilize a magnetic coil to produce a variable magnetic bias field in a ferrite rod. They offer full waveguide band operation and high-power handling compared to other technologies. Read the full story here:
When the strength or magnitude of a radio frequency (RF) signal must be reduced, attenuators are traditionally relied upon. They are especially useful for signal leveling or switching applications. At frequencies above 50 GHz, two electronically tunable variable attenuator technologies are most often employed: PIN diode and resistive vane attenuators. However, as outlined in a [...]
The move up the electromagnetic spectrum (EM) into millimeter waves (MMW) is proving to be a double-edged sword. System designers eager to leverage wider bandwidths and incredibly high data throughputs must also contend with a host of new challenges. Of amplified importance – particularly between 75-330 GHz – is the issue of attenuation. Read more [...]
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 [...]
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 [...]
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 [...]
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 [...]
