Radiotechnique (RT) was a French electronics company that made radio transmitting and receiving vacuum tubes, and later more advanced components such as integrated circuits and solar panels. At first it was a subsidiary of the French Compagnie générale de la télégraphie sans fil (CSF). Later it became a subsidiary of Philips of the Netherlands. The company expanded after World War II, moving into television and electronics, including photovoltaics and printed circuits, and in 1979 had about 15,000 employees. Later it lost market share, went through various restructurings, was sold in 1998 and went bankrupt in 2002.
