One of the most revolutionary innovations Raytheon has produced was the S gas rectifier tube. The device can eliminate the use of expensive batteries that power home radios. The tube was instrumental in transforming the radio into a “must-have” device that brought mass media communications to each American household.
The innovation moved Raytheon at the forefront of the electronics industry. During the World War II, Raytheon supplied 80% of the magnetron tubes for use in British and American radar systems. The company also developed a few parts for the proximity fuse of anti-aircraft shells.
After the WWII, Raytheon moved to civilian products that included the microwave. Through the years, Raytheon has built a reputation of leadership in technology and innovation.
