everything RF recently interviewed Diane Kees, the CEO of Micro Harmonics Corporation. Diane is a microwave engineer with deep expertise in ferrite devices for millimeter-wave applications, supported by advanced study in microwave engineering at the University of Virginia and specialized research on Faraday-rotation isolators and waveguide circulators. Since joining Micro Harmonics, she has played a leading role in the development and commercialization of high-frequency ferrite [...]

Researchers at IMRA America have demonstrated a new THz source architecture that overcomes several long-standing limitations. By combining a resonant tunneling diode (RTD), a photomixed dual-wavelength Brillouin laser, and a Micro Harmonics low-loss waveguide circulator, the team achieved more than 40 dB of gain at 260 GHz. Read the full story from everythingRF to learn about how this group became the first to characterize the [...]

Micro Harmonics' OMT proved essential to the success of a recent joint demonstration with VDI and Keysight to successfully transmit two independent wideband signals over a single 142 GHz link using orthogonal polarizations, effectively doubling data capacity. The breakthrough was enabled by Micro Harmonics’ high‑isolation, low‑loss OMT, which allowed 40 GHz of combined bandwidth to pass through one spatial path with exceptional signal integrity. This milestone paves [...]

A recent joint demonstration by VDI, Keysight, and Micro Harmonics successfully transmitted two independent wideband signals over a single 142 GHz link using orthogonal polarizations, effectively doubling data capacity. The breakthrough was enabled by Micro Harmonics’ high‑isolation, low‑loss OMT, which allowed 40 GHz of combined bandwidth to pass through one spatial path with exceptional signal integrity. This milestone paves the way for even higher‑capacity sub‑THz links, including [...]

An article published in EE Design It discusses a growing reality in mmWave system design: traditional attenuation approaches stop scaling once you push into the D-band. The story features our new WR-8 voltage-variable attenuator as the solution. That is because we addressed the problem, not with a refinement of conventional techniques, but by switching to a fundamentally different mechanism: Faraday rotation. Read the full story [...]

We are excited to announce the release of our newest millimeter-wave voltage-variable attenuator (VVA) that harnesses Faraday rotation technology. The WR-8 VVA is optimized for systems operating in the 90-140 GHz frequency range, delivering full band performance. Read the full release in Microwave Journal:

Keysight Technologies published a white paper on: 6G - A New Approach to Increasing Data Throughput. The company, in collaboration with Virginia Diodes, utilized our Orthomode Transducers (OMTs) in a new approach to combine the vertical and horizontal polarized signals into one dual-polarized signal to double the data throughput relative to a single-polarized transmission. This exploits orthogonal horizontal and vertical polarizations to transmit two independent [...]

An article in Microwave Product Digest discusses one of the central engineering challenges in sub-THz communication is the limited availability of hardware and the underlying components required for it to operate reliably at these frequencies. The story is about a recent effort led by Virginia Diodes, Inc. (VDI) and Keysight Technologies, using the Micro Harmonics OMT. The goal was to deliver clean, high-power, wideband signals [...]

Micro Harmonics Corporation has announced the release of its new mmWave orthomode transducer (OMT), engineered for high frequency applications requiring low loss, excellent polarization purity and wideband operation. The WR-3.4 orthomode transducer is optimized for systems operating in the 220 to 330 GHz frequency range, delivering performance that meets or exceeds stringent requirements for satellite communications, 5G/6G testbeds, radiometers and scientific instrumentation.

Polarization multiplexing is a proven approach for doubling data capacity in communication and sensing systems at lower frequencies. The challenge comes when trying to apply the same concept at sub-THz frequencies, especially with ultra-wideband signals, where maintaining signal integrity becomes far more complex. A recent article in EE Design It highlights how our OMT helped overcome this challenge. By combining high polarization isolation with low [...]
