What Eclipse Microdevices does
Eclipse Microdevices (Eclipse MDI) is a privately held, San Jose, California-based designer and manufacturer of broadband RF and microwave semiconductor components, founded in 2001. The company produces a broad portfolio of discrete and integrated RF devices operating from DC to 40+ GHz, including GaAs PHEMT MMIC driver and low-noise amplifiers, Zero Bias Schottky (ZBD) detectors, planar tunnel diode detectors and diodes, PIN-Schottky and Pin-Pin diode limiters, ultra-broadband directional couplers, double/triple balanced mixers, power dividers, frequency doublers, equalizers, and connectorized power modules. The product line is offered in QFN, ceramic, and coaxial package options and is positioned for 5G infrastructure, microwave test and measurement instrumentation, radar performance analysis, and pulsed RF applications, with select coupler and tunnel diode products qualified to MIL-E-5400, MIL-E-16400, and MIL-STD-190500 environmental standards.
The underlying technology rests on proprietary semiconductor process know-how: GaAs PHEMT MMIC design for amplifiers up to 33 GHz, ZBD Schottky detector fabrication for high-sensitivity detection up to 26.5 GHz, and planar tunnel diode construction on germanium substrates with all-gold metallization for high-reliability operation to +125°C. The tunnel diode product line was added in 2020 via a technology transfer arrangement with MACOM, expanding Eclipse's role as a second-source supplier for legacy tunnel diode customers. The portfolio is described as "100s of 5G-ready devices."
Eclipse sells to RF system designers and system manufacturers globally through a channel-based model: authorized sales representatives serve enterprise customers, distributors serve mid-market accounts, and a direct credit-card order form serves SMB and individual buyers. Pricing is quote-based and not publicly disclosed. Products are typically available for immediate shipment from stock. The company holds ISO 9001:2015, RoHS, REACH, and CCPA certifications. No revenue, funding, M&A, or leadership data are publicly disclosed.
