FMNS4002

Overview

The FMNS4002 is a surface-mount noise source module manufactured by Fairview Microwave, designed for RF testing and calibration applications. It operates within a frequency range of 0.2 MHz to 3 GHz. The device provides an Excess Noise Ratio (ENR) of 31 dB with a flatness of ±1.5 dB. It requires a +12 VDC power supply and utilizes a pin-packaged configuration for integration into circuit boards.

Feature Summary

• Surface-mount technology (SMT) design for compact PCB integration
• Wideband operation covering 0.2 MHz to 3 GHz
• High excess noise ratio (ENR) of 31 dB for reliable signal generation

Applications

• Noise figure measurement systems
• RF component characterization
• Receiver sensitivity testing

Procurement Notes

Verify the specific package variant and voltage requirements against the official datasheet before procurement. Confirm RoHS compliance status and check for any recent product change notices or obsolescence announcements from Fairview Microwave to ensure long-term availability and compatibility with current manufacturing processes.

Selection Notes

Select this module when a wideband noise source up to 3 GHz is required for SMT assembly. Ensure the system design supports the necessary +12 VDC supply and accounts for the thermal characteristics associated with surface-mount noise sources. Compare ENR specifications against test equipment requirements to validate suitability for precise noise figure measurements.

Part Context

This component belongs to Fairview Microwave's portfolio of RF modules and ICs, specifically categorized under noise sources. It serves as a critical test fixture component rather than a passive interconnect or cable assembly, distinguishing it from other products in the manufacturer's catalog such as coaxial cables or connectors.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Users should consult Fairview Microwave directly for potential cross-reference options or updated series replacements if this specific model becomes unavailable.
