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 at 142 GHz and beyond that could be transmitted and received with precision using just one beam. That meant combining two wideband signals, each occupying 20 GHz, into a single spatial path without interference. Read the full story about this RF breakthrough here:
