Raytheon awarded DARPA contract to help friendly forces communicate while conducting electronic warfare

Raytheon Company was awarded a $3.8 million contract from the Defense Advanced Research Projects Agency (DARPA) to allow armed forces to conduct jamming operations with minimal communication and control interference to friendly forces. The High-Power Efficient Rf Digital-to-Analog Converter (HiPERDAC) program seeks to enable tactical platforms, such as maritime craft, ground vehicles, tactical aircraft and unmanned aerial vehicles (UAVs), as well as individual soldiers, to conduct battlefield jamming operations while minimizing frequency interference with friendly forces. By generating signals that are both linear (that is, the ability of a signal to remain within a certain frequency) and efficient, HiPERDAC allows jamming across the frequency spectrum while providing precise gaps for communication frequencies used by friendly forces. Achieving signal linearity and efficiency has traditionally been very difficult, particularly at high power levels.
