Today’s Multifunction Active Electronically Scanned Array (AESA) systems are engineered and manufactured to simultaneously perform different operations, such as radar, electronic warfare (EW), and communications functions. One of the most critical elements of digitally reprogrammable multifunction AESA systems are the fixed-frequency sources.

Building for space is challenging. Program management requirements, parts availability and delivery, parts costs, and testing costs historically make space OCXOs expensive and longlead. Standardizing specifications based on MIL-PRF-55310, NASA EEE-INST-002, NASA Parts Selection List, and GSFC Preferred Parts Lists, and procuring parts to vendors standard drawings can significantly reduce costs and improve delivery of high-performance OCXOs.

As access to and utilization of the low Earth orbit (LEO) region has expanded, so too has demand increased for affordable, mass producible space-worthy timing devices. In this white paper, Quantic Wenzel outlines the approach, process, and results of adapting and qualifying an established family of ONYX oscillators to production for commercial LEO space applications.
