Company Overview

Frequency Electronics, Inc. operates in the precision timing, frequency generation, and synchronization technology industry, serving aerospace, defense, telecommunications, and government markets. The company designs and manufactures high-performance quartz oscillators, atomic clocks, frequency reference systems, synchronization products, and microwave integrated assemblies used in satellites, secure communications systems, electronic warfare platforms, and space missions. Its products are typically deployed in applications where long-term timing stability, signal integrity, and reliability under extreme environmental conditions are critical.

The company’s primary revenue drivers include space-qualified timing systems, satellite payload components, U.S. government and defense contracts, and precision frequency control products for commercial and industrial customers. Frequency Electronics has historically maintained a niche strategic position through its expertise in ultra-precise timing technology, vertically integrated engineering capabilities, and long-standing relationships with U.S. defense agencies and aerospace contractors. Founded in 1961 and headquartered in Mitchel Field, New York, the company evolved from a commercial frequency-control manufacturer into a specialized supplier for high-reliability defense and space programs.
