Frequency Electronics designs and manufactures precision time and frequency generation systems used in commercial and U.S. Government satellites, command and control systems, and electronic warfare platforms. The company operates two principal segments: FEI-NY (Long Island) produces satellite electronics and RF microwave modules for government and commercial customers, while FEI-Zyfer (California) manufactures precision timing references and GPS-based products primarily for secure government communications. The company generates revenue through fixed-price and cost-plus contracts primarily with the U.S. Government and major defense contractors such as Northrop Grumman and Lockheed Martin, competing on product accuracy, reliability, performance in extreme conditions, and responsive execution.
