Heterogeneous Integration Technology enhance capability of military RADAR, communications, imaging and sensing systems, DARPA’s DAHI, and CHIPS led its development

Modern warfare is increasingly dependent on microelectronics capabilities that sense the environment, convert the signals into data streams, process the information, and generate a response. In this sense, Aerospace and Defense (A-D)  systems are quite similar to commercial systems that perform communications and computations, while taking advantage of the advancement of semiconductor density, functionality, and cost reduction due to Moore’s Law. There is the everincreased demand for more data throughput through wired and wireless systems. Cellular systems have migrated from 3G to 4G and now 5G architectures which improves bandwidth ~10X with each generation. DoD systems for communications, radar, and sensing generally require wider bandwidths, higher dynamic range, and higher transmit power, as well as specialized frequency bands and security requirements that the commercial side does not require.
