Digital Instantaneous Frequency Measurement receivers (DIFMs) are functional building blocks in many Military Electronic Warfare systems, including Electronic Counter Measures systems (ECM), Electronic Surveillance Measures systems (ESM), and Radar Warning Receivers (RWR).

LNX Corporation's latest DIFMs benefit from our heritage of being successfully integrated into six systems in the past two years. Our product design philosophy employs tools which address any new requirement:

• Broadband fundamental microwave components (2.0 to 18.0 GHz and 0.5 to 2.5 GHz) guarantee frequency coverage for any application.
• Firmware based field programmable logic accommodates any digital interface requirement that the customer can define.
• State-of-the-art microwave and digital building blocks ensure frequency accuracy specification compliance for all customers.
• State-of-the-art mechanical and electrical design tools are used to minimize development time and create products of optimum electrical performance, and mechanical parameters (size and weight).
• Extensive experience in designing components and subsystems for military applications ensures products that are reliable and manufacturable.
• Extensive in-house manufacturing ensures the ability to maintain production rates and keep schedules on time.
