PE85NS4002

Overview

The PE85NS4002 is a surface mount noise source module manufactured by Pasternack. It operates within a frequency range of 0.2 MHz to 3 GHz and provides an excess noise ratio (ENR) output of 31 dB. The component requires a +12 VDC power supply for operation. Designed for general-purpose RF applications, it utilizes a pin-packaged surface mount technology (SMT) form factor. This device serves as a calibrated noise reference for testing and characterization of RF systems across the specified bandwidth.

Feature Summary

• Surface mount pin-packaged construction for automated assembly integration
• Provides stable 31 dB excess noise ratio for system calibration
• Operates on a standard +12 VDC power supply requirement

Applications

• RF receiver sensitivity testing
• Noise figure measurement systems
• General-purpose RF component characterization

Procurement Notes

Verify that the specific part number matches the required ENR value of 31 dB and the 0.2 MHz to 3 GHz frequency range. Confirm compatibility with the +12 VDC supply voltage in your design. Ensure the surface mount package type aligns with your PCB layout constraints. Cross-reference official datasheets to validate performance specifications before procurement.

Selection Notes

Select this component when a surface mount noise source is required for frequencies up to 3 GHz. The 31 dB ENR level suits applications needing a distinct noise step for accurate measurements. Verify that the +12 VDC supply is available in the target environment. Consider the SMT footprint dimensions during mechanical design to ensure proper placement and thermal management.

Part Context

This module belongs to Pasternack's line of RF noise sources designed for test and measurement equipment. It complements other calibration components by providing a known noise reference. The surface mount format distinguishes it from bulkier connectorized alternatives, facilitating integration into compact modern RF circuits and automated test fixtures.

Replacement Considerations

No public confirmed substitute part numbers are identified in the provided documentation. When evaluating alternatives, match the 0.2 MHz to 3 GHz frequency range, 31 dB ENR specification, and +12 VDC supply requirement. Ensure any replacement supports the same surface mount package style to maintain PCB compatibility.
