Channel Technologies Group (CTG) is a privately held firm located in California, specializing in the development and production of piezoelectric materials and transducers for both defense and commercial sectors.

Founded in 1959 by Robert F. Carlson and Bob Callahan, CTG’s headquarters are situated in Santa Barbara, California, complemented by a manufacturing plant in Bolingbrook, Illinois. The company’s offerings encompass piezoelectric ceramics, single crystal materials, transducer devices, complete sonar system solutions, as well as electro-optical calibration and testing instruments. CTG caters to a variety of industries including medical technology, marine exploration, energy, and defense, with prominent clients such as the U.S. Navy and leading defense contractors.

The organization maintains 150,000 square feet of production space that includes a prototype manufacturing line, a materials research lab, a machine shop, and comprehensive testing facilities. Its enterprise resource planning (ERP) platform facilitates centralized order processing and component tracking throughout the manufacturing cycle, promoting efficient lean production methodologies.

Owned by Blue Wolf Capital Partners LLC, CTG employs around 250 staff members. Despite its established market position and advanced technological assets, the company filed for bankruptcy protection in 2016 following losses exceeding $10 million on long-duration contracts.
