We design and manufacture piezoelectric materials, transducers, turnkey integrated systems and optical solution technologies that support mission critical applications for military and essential commercial market platforms.

Based in Santa Barbara, Calif. and with a second manufacturing site in Littleton Massachusetts, Channel Technologies Group (CTG) first began manufacturing piezoelectric ceramics in 1959. Since that time, CTG has grown and developed unparalleled in-house expertise, allowing CTG to expand its product offerings to include piezoelectric ceramics, transducers, turnkey sonar systems and electro-optical calibration and testing equipment.
