API Technologies

In January 2023 API Technologies (APITech) changed its name to Spectrum Control. The Spectrum Control name (part of our legacy of acquired companies) better represents the new direction of the company and pays homage to our strong legacy. Fundamentally our name now says what we do: provide our customers with products and solutions to control the electromagnetic spectrum.

APITech combined engineering expertise, innovation and manufacturing excellence to enable mission-critical solutions. Designed to solve complex problems in signal modulation and transmission, API solutions enabled high quality product performance in the military and government, space, commercial, aerospace, security, medical, industrial and communications industries. Through proven experience and innovation, API delivered reliable solutions for the most rugged, harsh environments in the world – and beyond.
