The Defense Advanced Research Projects Agency has named the research teams who will work on a program to develop technologies that could help mitigate interference for broadband radio frequency systems.
Teams from BAE Systems, Raytheon Technologies and its Collins Aerospace business, Northrop Grumman, Indiana Microelectronics and the University of Pennsylvania will explore the development of tunable filters in the 2-18 GHz band of interest as part of the Wideband Adaptive RF Protection program , DARPA said Wednesday.
L3Harris Technologies, BAE, Columbia University and the University of Pennsylvania will build reconfigurable signal cancellers in the 0.1-6 GHz band of interest as part of the second research area of the WARP program.
“WARP performers are exploring a range of innovative approaches to developing new circuit architectures for tunable filters and cancellers,” said DARPA program manager Timothy Hancock.
“Adaptive filter technology is expected to help protect wideband digital receivers from signal saturation in crowded environments and adaptive cancellers will enable same frequency simultaneous transmit and receive (STAR) applications. over much wider bandwidths than can be achieved today,” Hancock said. added.
