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 [...]
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 [...]
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 [...]
