StratEdge Corporation in Santee designs, manufactures, and assembles high-frequency semiconductor packages operating from DC to 63-plus GHz at its ISO 9001:2015-certified and ITAR-registered facility on Abraham Way. Founded in 1992, the company specializes in post-fired ceramic and molded ceramic packaging for gallium arsenide and gallium nitride devices used in 5G telecom, satellite, defense, and test-and-measurement applications, sharing Santee's engineering corridor with firms such as Allied Geotechnical Engineers on Cuyamaca Street. The Santee division's Class 1000 cleanroom includes Class 100 work areas with full ESD control, housing automated die-bonding and wire-bonding equipment calibrated for sub-six-micrometer eutectic gold-tin attachment. Over 200 standard package outlines are available in leaded drop-in, leadless surface-mount, and ceramic QFN configurations, all manufactured lead-free and compliant with RoHS and WEEE standards — a precision-manufacturing ecosystem supported by Santee's broader technology cluster that includes EnSight Technologies on Prospect Avenue. Highest-tier assembly services involve multi-chip MMIC modules with 50-ohm impedance transitions, eutectic die attach at bond-line thicknesses below six micrometers, and automated wire bonding calibrated for consistent loop height across millimeter-wave frequencies.
