Spacek Labs

What Spacek Labs does

Spacek Labs is a privately held, family-owned manufacturer of millimeter-wave and microwave components and sub-systems founded in 1982 and headquartered in Santa Barbara, California. The company operates across a 10,000 square foot facility with two adjacent industrial buildings housing 30 assembly and test benches spanning 2 to 110 GHz, vector network analyzers to 65 GHz, a Faraday cage screen room, environmental chambers from -55C to +165C, and in-house cryogenic testing capability down to 15 Kelvin. Its core technology covers solid-state amplifiers, frequency multipliers, mixers, filters, detectors, Gunn oscillators, frequency synthesizers, and waveguide components built on waveguide technology across WR-42 to WR-10 bands.

The company sells both a catalog of standard components and custom-designed solutions, with approximately 30% of revenue from custom engineering work for defense and government customers requiring MIL-spec or space-qualified reliability levels. Product portfolio spans Microwave and Millimeter-Wave Amplifiers, Broadband Detectors, Filters (ultra-wide bandpass, narrow bandpass, low-pass, high-pass), Frequency Sources (Gunn oscillators, frequency synthesizers, phase-locked sources), Mixers/Frequency Converters (receivers, transmitters, transceivers, downconverters, upconverters), Frequency Multipliers, and Waveguide to Coax Adapters, plus subsystem-level products such as Radiometer Front-Ends. Recent launches have extended the portfolio into 5G Frequency Range 2 commercial telecom, Ka-Band transceivers, and V-Band filters.

Distribution operates through direct sales from the Santa Barbara headquarters via website quote requests, phone, and email ([email protected]), complemented by a global network of eight appointed sales representatives and distributors covering the United States, United Kingdom, France, Germany, Spain, Portugal, Japan, and India. Marketing leverages a content-driven website, industry conference participation (IMS, EDI CON USA, European Microwave Week), email newsletter, and social media presence. The company is ISO 9001:2015 certified and is also described as a woman-owned business, with Michael Wilson serving as CEO and President.
