Abstract (strongly encouraged) due May 5, 2021
Proposal due June 18, 2021

The DARPA Microsystems Technology Office is soliciting innovative research proposals to develop compact, low-noise microwave frequency synthesizers to enable advanced sensing and communication applications.
The GRYPHON program seeks to leverage the advantages of photonic microwave generation to develop integrated sources with phase noise performance that meets or exceeds that of the best discrete oscillator modules (e.g., oven-controlled crystal oscillators (OCXO), oven-controlled SAW oscillators, and dielectric resonator oscillators (DRO)), yet occupy a compact volume typical of far noisier chip-scale voltage controlled oscillators (VCO) (e.g., monolithic microwave integrated circuits (MMIC), Yttrium Iron Garnet (YIG), and uncompensated XOs). Moreover, by program end, GRYPHON microwave sources will operate as synthesizers with the ability to tune to any frequency from 1 – 40+ GHz during operation. This combination of features is unprecedented in today’s state of the art, and will establish a new regime of source technology that is expected to transform the types and capabilities of military and commercial microwave systems. GRYPHON will pursue advanced prototype development as well as research studies into novel microwave generation techniques and components. In addition to the primary focus on performance and integration, later program phases will harden GRYPHON prototypes to basic environmental stresses sufficient to validate the technology for application-specific maturation after the conclusion of the program.
