Spectrum Control, Inc.

Spectrum Control, Inc. designs and manufactures technologies for managing the electromagnetic spectrum. Its work spans four main areas: RF and microwave signal powering and conditioning, microelectronics, electromagnetic interference (EMI) management and control, and security technologies. The company supplies components and systems used where signal integrity and protection are critical, including defense, aerospace, medical, electronics and telecommunications.

The product portfolio is built around three core technology areas. RF and microwave offerings cover high-performance signal powering and conditioning, forming part of a broader signal conditioning and protection range. Microelectronics technologies sit alongside these, as do security technologies aimed at contested and mission-critical environments. The underlying engineering focus is on solving complex signal conditioning and protection problems.

Founded in 1968 by three engineers from Erie Technical Products Inc., the company grew from a regional start-up into an international business. It maintains facilities in four countries: the United States, Canada, Mexico and the United Kingdom, with its origins in Erie, Pennsylvania. Its stated emphasis on mission-critical reliability reflects the demands of the industries it serves.
