FMNS4003

Overview

The FMNS4003 is a surface mount noise source module manufactured by Fairview Microwave, designed for RF testing applications. It operates within a frequency range of 200 kHz to 2 GHz and delivers an excess noise ratio (ENR) of 51 dB. The device requires a +12 VDC power supply and utilizes a pin-packaged configuration suitable for surface mount technology.

Feature Summary

• Provides high excess noise ratio for accurate calibration
• Supports surface mount integration
• Operates across broad frequency spectrum

Applications

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

Procurement Notes

Verify the specific package variant and voltage tolerance against the official datasheet before integration. Confirm that the +12 VDC supply requirements align with your system design. Ensure the surface mount footprint matches your PCB layout constraints. Check for any updated revision notes regarding the pin configuration.

Selection Notes

Select this module when a compact, surface-mount noise source is required for frequencies up to 2 GHz. The 51 dB ENR provides significant signal margin for precise measurements. Consider the thermal management capabilities inherent in the surface mount package for continuous operation scenarios.
