DARPA is soliciting innovative proposals that demonstrate integration of technology that has been developed in the COFFEE program.

The drive toward wideband, digital-at-every-element, active electronically scanned arrays (AESAs) has increased AESA capabilities but left them vulnerable to interferers. To mitigate the impact of interferers, DARPA set out to develop compact, high-performance radio frequency (RF) filter technology through Technical Area 1 of the COFFEE program.

Recent spectrum allocations for FutureG and satellite communications, among others, create new commercial opportunities but risk signal interference with incumbent Department of Defense systems. Notably, these new spectrum allocations are in the frequency range addressed by COFFEE RF filters. Thus, breakthroughs in RF filter technologies made in COFFEE now have the potential to radically address the challenges of signal interference across the DoD and in many commercial applications. This COFFEE Technical Area 2
seeks to demonstrate the newly expanded potential of COFFEE technology.

COFFEE TA2 will capitalize on the breakthroughs in RF filter size and performance made during the COFFEE program by integrating COFFEE filters into exemplars that demonstrate interference suppression.

COFFEE TA2 is a single-phase (18-month) effort that will validate all Technical Challenges of COFFEE BAA1 by integrating 2–18 GHz (or a subset of) filters with as-needed external components (eg switches, controls, interconnects, interposer, etc.) into a filter tile. TA2 will culminate with the delivery of integrated filter tiles that meet the performance metrics and constraints. This will demonstrate the potential for scalable manufacturing and interference suppression.

Abstracts (encouraged, but not compulsory) are due 4 June 2024, with final proposals due 2 August 2024.
