PE1641

Overview

The Pasternack PE1641 is a coaxial cable assembly featuring SMA connectors. It utilizes semi-rigid construction with a silver-plated copper alloy center conductor and PTFE dielectric for stable electrical performance across frequencies up to 18 GHz. The assembly incorporates a gold-plated beryllium copper contact interface to ensure reliable signal transmission. Its outer jacket is made of PTFE, providing chemical resistance and durability in demanding environments.

Feature Summary

• Semi-rigid coaxial design ensures consistent impedance and phase stability
• Gold-plated beryllium copper contacts provide durable connection integrity
• PTFE dielectric material supports high-frequency signal fidelity

Applications

• Test and measurement instrumentation interconnects
• Aerospace and defense communication systems
• RF module integration requiring precise phase characteristics

Procurement Notes

Verify the specific connector gender and cable length requirements against your system schematic before ordering. Confirm that the operating environment temperature range aligns with the PTFE material specifications. Ensure mating connectors match the SMA interface type to prevent mechanical damage. Request updated test reports if phase stability data is critical for your application validation.

Selection Notes

Select this model when semi-rigid performance is required over flexible alternatives. Consider the fixed length constraints inherent to semi-rigid assemblies during routing planning. Evaluate the need for gold plating versus silver plating based on corrosion resistance needs. Verify that the SMA interface compatibility matches existing panel or board mount hardware.

Part Context

This component belongs to Pasternack's line of precision RF cable assemblies designed for high-frequency applications. It serves as a specialized interconnect solution where signal integrity and mechanical rigidity are prioritized over flexibility. The product targets industries requiring repeatable performance in complex RF signal paths.

Replacement Considerations

No direct public substitute part numbers are documented for this specific configuration. Alternative solutions may require custom fabrication to match the semi-rigid construction and SMA interface specifications. Verify dimensional tolerances and electrical parameters when considering generic equivalents.
