What Sage Millimeter, Inc. does
Sage Millimeter, Inc. — operating commercially as Eravant and formerly known as SAGE Millimeter — is a Torrance, California-based designer and manufacturer of millimeter wave and sub-THz components, subassemblies, antennas, and test equipment covering the DC to 330 GHz frequency range. Founded in 2011 by two veterans of the millimeter wave industry, the company operates a 60,000-square-foot vertically integrated facility that includes design, machining, assembly, an ISO Class 8 cleanroom module build line for space/military applications, and an extensive in-house RF test infrastructure (50+ scalar network analyzers, 30 vector network analyzers, power measurement capability to 1 THz). Its catalog exceeds 5,000 unique commercial-off-the-shelf (COTS) models spanning passive components (waveguides, antennas, filters, couplers, attenuators, terminations), active devices (amplifiers, multipliers, oscillators, mixers), test and measurement equipment, automated test equipment, and TX/RX modules, supplemented by proprietary products such as the Proxi-Flange™ contactless flange, the patent-pending Wave-Glide™ VNA Rail System, and the Uni-Guide™ waveguide connector.
The firm monetizes primarily through direct hardware sales of COTS components and custom subassemblies, distributed via a login-gated e-commerce storefront and a direct enterprise sales motion that supports customers from lab setup through R&D, prototype, and volume production phases. Pricing is quote-based and not publicly disclosed. Customer segments include aerospace and defense (SATCOM, radar, electronic warfare), commercial communications (5G FR2 bands 37–98 GHz, SATCOM infrastructure), radar and sensing (automotive and industrial Doppler/ranging), and research/testing laboratories (calibration, TVAC, antenna pattern measurement). The company is a women-owned small business holding AS9100D (with ISO 9001:2015), ISO 14644-1 cleanroom, ITAR registration, and NIST 800-171/CMMC Level 2 cybersecurity certifications, and serves a global customer base with its products compatible with Keysight, Rohde & Schwarz, and Anritsu vector network analyzers.
Commercially, Sage Millimeter remains a private, founder/management-controlled entity with no disclosed outside investors, no disclosed funding rounds, and no disclosed headcount or revenue figures. The company shows no indication of acquisition, closure, or public-listing intent; its operating signals — proprietary product launches, expanding application coverage (radar sensors, 5G FR2, new space/TVAC), and accumulation of defense-grade certifications — point to organic, vertically integrated growth in the aerospace, defense, and high-frequency communications supply chain.

Sage Millimeter, Inc. competitors and assessment
Company assessmentDirect peers
- Flann Microwave: Flann manufactures precision waveguide components, antennas, and instrumentation across microwave and mmWave bands. The product mix and target customers in defense, telecom, and scientific research are highly comparable to Eravant.
- QuinStar Technology: QuinStar designs and manufactures millimeter-wave and sub-millimeter-wave components, subsystems, and antennas for aerospace, defense, and telecom applications—directly overlapping with Eravant's waveguide, coaxial, and test-equipment portfolio.
- Narda-MITEQ: Narda-MITEQ designs and manufactures RF/microwave components, subassemblies, and integrated subsystems for defense and commercial customers. It competes head-to-head with Eravant in passive components, mixers, and mmWave subsystems.
- Mi-Wave: Mi-Wave supplies millimeter-wave components, antennas, and test equipment in the 26.5-500 GHz range. Its frequency coverage, waveguide component catalog, and target markets in research, aerospace, and communications closely match Eravant's scope.
- RLC Electronics: RLC makes coaxial and waveguide RF/microwave components including switches, filters, attenuators, and couplers. Its catalog-driven approach to mmWave and microwave components makes it a directly comparable specialty supplier.
- Millimeter Products Group (MPG): MPG specializes in millimeter-wave antennas, components, and instrumentation for defense and commercial communications. Its focus on mmWave antennas and integrated assemblies overlaps with Eravant's antenna, radar, and TX/RX module lines.
Broad incumbents
- Rohde & Schwarz: Rohde & Schwarz is a leading manufacturer of VNAs and signal/spectrum analyzers compatible with Eravant's extenders. Its broad test-and-measurement portfolio and mmWave options place it as a large incumbent adjacent to Eravant's customer set.
- Keysight Technologies: Keysight is the dominant vendor of VNAs, spectrum analyzers, and signal generators that Eravant's extenders plug into. It also sells its own mmWave components and modules, making it both an integration partner and a broad incumbent competitor.
- Pasternack (Infinite Electronics): Pasternack operates a much broader RF/microwave catalog spanning connectors, cables, antennas, and active components across DC to 50+ GHz. It competes with Eravant on standardized COTS RF components but at lower mmWave bands and with vastly larger scale.
- Anritsu: Anritsu is a major supplier of VNAs and handheld RF/microwave test instruments that Eravant extenders are designed to work with. It competes broadly in mmWave test and measurement alongside Eravant's ACCESS T&M and frequency extender lines.
