DARPA is soliciting innovative proposals for the RAAPTR program to develop RF system architectures that maintain optical timing precision in rugged, compact forms for mobile land, air, and space defense platforms. The focus is on vibration-hardened photonic oscillators, low phase noise analog and mixed-signal components, and advanced subsystem architectures for defense applications. Research that advances non-optical microwave generation or merely improves existing methods is excluded. Additional program details are provided in a Controlled Unclassified Information (CUI) addendum, with instructions for requesting it included in Attachment A.

DARPA is soliciting innovative proposals for the RAAPTR program to develop radiofrequency (RF) system architectures that maintain optical timing precision in rugged form factors for compact mobile land, air, and space-based defense platforms. The program seeks advances in vibration-hardened, ultra-low phase noise photonic oscillators; vibration-hardened low phase noise analog and mixed-signal components; and high-performance analog and digital subsystem architectures for defense-relevant use cases. Research advancing non-optical microwave generation or making only evolutionary improvements is excluded. A Controlled Unclassified Information addendum with additional program details is available upon request. No specific budget, location for performance, or submission timelines are indicated in the provided description.
