PE7090-30

Overview

The Pasternack PE7090-30 is a coaxial cable assembly featuring SMA connectors. It utilizes semi-rigid construction with a silver-plated copper outer conductor and PTFE dielectric for stable electrical performance across the frequency range of DC to 18 GHz. The assembly incorporates a 30-foot length of RG405 type cable, providing a characteristic impedance of 50 Ohms. This configuration ensures low insertion loss and high return loss, suitable for precision RF applications requiring durable connections in test and measurement environments.

Feature Summary

• Semi-rigid construction utilizing silver-plated copper outer conductors for enhanced durability and conductivity
• PTFE dielectric material ensuring consistent electrical characteristics and phase stability over temperature variations
• SMA male-to-male connector configuration designed for secure mating and reliable signal transmission

Applications

• RF test and measurement setups requiring precise signal integrity
• Aerospace and defense electronic systems integration
• Telecommunications equipment testing and validation

Procurement Notes

Verify that the specific order matches the required cable length and connector gender combination. Confirm that the operating environment temperature range aligns with the PTFE dielectric specifications. Ensure that the SMA connector interface compatibility matches existing system hardware to prevent mating issues. Check for any specific environmental sealing requirements if the assembly will be exposed to moisture or harsh conditions during operation.

Selection Notes

Select this model when long cable runs are necessary within semi-rigid performance constraints. Consider the weight and bend radius limitations inherent to semi-rigid cables compared to flexible alternatives. Evaluate the need for silver plating versus gold plating based on corrosion resistance requirements and contact resistance priorities. Assess whether the fixed 30-foot length meets spatial constraints without requiring custom fabrication services.

Part Context

This component belongs to the Pasternack semi-rigid coaxial cable assembly series. These assemblies bridge the gap between flexible cable convenience and rigid line performance. The series typically offers various lengths and connector combinations. The PE7090 series specifically focuses on SMA interfaces. This positioning supports applications demanding high-frequency stability and mechanical robustness in compact RF designs.

Replacement Considerations

Direct replacements must match the SMA male-to-male configuration and 50 Ohm impedance. Verify that substitute assemblies maintain the same RG405 cable type or equivalent electrical performance. Ensure the replacement part supports the DC to 18 GHz frequency range. Confirm physical dimensions and bend radius capabilities fit the installation space.
