From 54 GHz to 330 GHz, we have developed a complete family of broadband hybrid circulators for millimeter-wave and sub-THz applications. At these frequencies, a circulator is no longer just another component in the signal chain. It becomes an enabling technology. #circulators

At the International Microwave Symposium (IMS), Virginia Diodes, Inc. (VDI) demonstrated how our VVA gave their system a controllable element at the high-frequency side of the chain. Watch a video of the demo here: lnkd.in/gq3ehESt #voltage variable attenuation

When performance matters, measured data matters. That's why every Micro Harmonics mmWave component is: - Designed for exceptionally low insertion loss - Built to handle high RF power - Individually characterized across the full waveguide band Learn more lnkd.in/g5k_78JY

Our orthomode transducer was used to combine independent horizontally and vertically polarized signals into a single dual-polarized sub-THz beam, helping enable two simultaneous data streams over one link. Read the full Keysight article here: lnkd.in/g_52hqYj #6G #SubTHz

One of the more interesting demonstrations at #IMS this year came from IMRA America, Inc., which showcased a #photonic #THz source stabilization setup using optical frequency locking and OCS spectroscopy. This system utilized our WR-3.4 full-band hybrid #circulator. Great work!

RF testing of orthomode transducers (OMTs) presents a unique challenge because the common-mode port supports two orthogonal modes, while vector network analyzers use single-mode test ports. For a more detailed explanation of OMT testing, read our blog: lnkd.in/g7HaGpPV

By combining a resonant tunneling diode (RTD), a photomixed dual-wavelength Brillouin laser, and our low-loss waveguide circulator, the IMRA team demonstrated more than 40 dB of gain at 260 GHz. For details on this breakthrough, read the full article here: lnkd.in/g5PHVw3h
