PE85NS4001

Overview

The PE85NS4001 is a surface mount noise source module designed for general-purpose RF applications. It operates within a frequency range of 200 kHz to 2 GHz and requires a +12 VDC supply voltage. The device provides an Excess Noise Ratio (ENR) of 31 dB with a flatness specification of ±1.5 dB. Packaged in a compact SMT pin configuration, it serves as a stable reference signal generator for calibration and testing systems requiring precise noise figure measurements across wide bandwidths.

Feature Summary

• Surface mount pin packaged construction for automated assembly integration
• Provides high excess noise ratio for accurate measurement references
• Operates on standard single DC supply voltage

Applications

• RF component characterization and testing
• Noise figure analyzer calibration
• Receiver sensitivity measurement setups

Procurement Notes

Verify the specific package outline dimensions against your PCB footprint design prior to ordering. Confirm that the required +12V supply capability matches your system power architecture. Ensure the operating temperature range aligns with your environmental specifications. Cross-reference the datasheet revision date to ensure compatibility with current manufacturing standards.

Selection Notes

Select this model when a wideband noise source from 200 kHz to 2 GHz is required for calibration tasks. Consider the 31 dB ENR level relative to your measurement dynamic range needs. Evaluate the SMT form factor against available board space constraints. Compare the ±1.5 dB flatness specification against the accuracy requirements of your specific test application.

Part Context

This component belongs to Pasternack's line of RF miscellaneous modules and ICs. It functions specifically as a noise source rather than a passive attenuator or active amplifier. The product series focuses on providing standardized signal sources for laboratory and production test environments where consistent noise generation is critical for equipment validation.

Replacement Considerations

No public confirmed substitute part numbers are documented for this specific model. Direct replacement may require verifying interface compatibility and electrical parameter equivalence with alternative vendors. Consult manufacturer documentation for any discontinued part cross-references.
