FMNS4001

Overview

The FMNS4001 is a surface-mount RF noise source module manufactured by Fairview Microwave. It operates within a frequency range of 200 kHz to 2 GHz and provides an excess noise ratio (ENR) of 31 dB. The device requires a maximum supply voltage of 12 VDC and utilizes an 8-SMT package configuration. Designed for precision calibration, this component serves as a stable reference signal generator for radio frequency testing environments.

Feature Summary

• Generates calibrated noise signals for system verification
• Surface mount construction for automated assembly integration
• Operates with standard DC power supply requirements

Applications

• Vector Network Analyzer (VNA) calibration
• Noise figure measurement systems
• RF receiver sensitivity testing

Procurement Notes

Verify the specific datasheet version to confirm pinout assignments and thermal management requirements for your PCB layout. Ensure that the power supply circuitry strictly adheres to the 12 VDC maximum limit to prevent component damage. Cross-reference the operating temperature range with your environmental specifications before finalizing the procurement order.

Selection Notes

Select this module when a wideband noise source is required for calibrating measurement equipment across the specified frequency spectrum. Consider the surface mount form factor if space constraints or high-volume production automation are primary design drivers. Evaluate the 31 dB ENR specification against the dynamic range requirements of your target test setup.

Part Context

This component belongs to the RF modules category, specifically designed as a noise source for electronic test and measurement applications. It complements other RF accessories by providing a known noise reference, enabling accurate characterization of receiver performance and system noise floors in laboratory and field testing scenarios.
