Executives at Raytheon Co. in Lexington, Mass. are selling the monolithic microwave integrated circuit (MMIC) operations of the former Texas Instruments Defense Systems & Electronics Group to TriQuint Semiconductor Inc. of Hillsboro, Ore., for $39 million. The selloff of the TI MMIC operation was part of an agreement with the U.S. government under which the recent Raytheon acquisition of TI Defense was approved. Electronic systems designers use MMIC devices in military and commercial applications such as radar, missile systems, point-to-point digital radios, wireless systems, and satellite communications. TriQuint manufactures RF, analog, and mixed-signal gallium arsenide ICs. - J.K.
