1 History

Two former college roommates Laurence K. Marshall and Vannevar Bush, along with scientist Charles G. Smith , founded the American Appliance Company in Cambridge, Massachusetts in 1922. The company's first product was a gaseous rectifier, called the Raytheon ("light of the gods") and used for radio-receiver power supplies that plugged into the power grid in place of large batteries. The company changed its name to Raytheon in 1925.

Raytheon also manufactures semiconductors for the electronics industry. In the late 20th century it produced a wide range of integrated circuits and other components, but as of 2003 its semiconductor business specializes in gallium arsenide components for radio communications. It also makes several software radio and digital communication systems for military applications such as Cooperative Engagement Capability (CEC), is participating in Navy-Marine Corps Intranet (NMCI), Echelon and the Joint Tactical Terminal (JTT) programs. Civilian lines of business include corporate jet aircraft.
