What Eravant does

Eravant (formerly SAGE Millimeter, Inc.) is a US-based designer and manufacturer of millimeter wave and sub-THz components and test equipment, founded in 2011 by two veterans of the millimeter wave industry and headquartered in a 60,000-square-foot facility in Torrance, California. The company operates four business units spanning DC to 330 GHz, offering over 5,000 commercial-off-the-shelf (COTS) models across waveguide components (18–330 GHz), coaxial components (DC–110 GHz), test and measurement equipment, antenna measurement systems, radar products, and 5G FR2 communication components. Core proprietary technologies include the Proxi-Flange™ contactless flange, the patent-pending Wave-Glide™ VNA Rail System, and the Uni-Guide™ waveguide connector, alongside VNA frequency extenders compatible with Rohde & Schwarz, Anritsu, and Keysight analyzers.

Eravant monetizes through multiple streams: (i) direct e-commerce sales of COTS components from its online catalog, (ii) quote-based custom solutions and subassembly design/manufacturing, and (iii) professional services including calibration and measurement (50–330 GHz), antenna pattern measurement using 2D/3D far-field anechoic chambers, and environmental/TVAC testing. The customer base is global and vertically segmented, with aerospace & defense and satellite communications designated as primary use cases, supplemented by automotive/industrial radar and academic/commercial R&D.

The company is AS9100D (and ISO 9001:2015) certified, ITAR registered, ISO 14644-1 cleanroom certified, and NIST 800-171 / CMMC Level 2 compliant — credentials that materially enable participation in defense and space supply chains. It is also a US Small Business Administration–certified women-owned small business. Capital intensity is significant: the facility houses 50+ scalar network analyzers, 30 vector network analyzers, and 20 spectrum analyzers supporting test capabilities up to 325 GHz and power measurement to 1 THz, an inventory base that is difficult for new entrants to replicate. Eravant supports customers across the full lifecycle — lab setup, R&D, prototyping, and volume production — combining catalog self-service with enterprise field sales.
