PE8031

Overview

The Pasternack PE8031 is a high-power RF limiter module designed for signal protection. It features an SMA connector interface and operates within the 2 GHz to 4 GHz frequency range. The device handles a peak power of 200 Watts with a recovery time of 200 microseconds. Electrical performance includes a maximum insertion loss of 0.8 dB and a flat leakage level of 14 dBm. The unit utilizes a PIN-Schottky technology architecture housed in an SMA in-line package, ensuring reliable operation across a temperature range of -55°C to 90°C.

Feature Summary

• Provides automatic signal attenuation to protect sensitive downstream components from high-power RF exposure.
• Utilizes PIN-Schottky technology for rapid response and stable limiting characteristics.
• Engineered for low insertion loss to minimize signal impact during normal transmission.
• Features a robust SMA in-line module form factor for easy integration.

Applications

• Base station transmitter output protection
• Radar system component safeguarding
• Test and measurement equipment input protection
• Communication infrastructure signal conditioning

Procurement Notes

Verify that the specific SMA connector orientation matches the system design requirements. Confirm that the operational frequency range aligns with the intended application spectrum. Ensure thermal management capabilities meet the environmental conditions specified for the installation site. Check datasheet revisions for any updates to electrical specifications or mechanical dimensions prior to finalizing procurement orders.

Selection Notes

Select this component when protecting circuits against peak powers up to 200 Watts within the 2-4 GHz band. Consider the 0.8 dB insertion loss impact on overall system gain. Evaluate the 200 microsecond recovery time against pulse repetition requirements. Compare physical dimensions and mounting options against available space constraints in the assembly.

Part Context

This part belongs to Pasternack's portfolio of high-power RF limiters. It serves as a protective element within radio frequency systems, distinguishing itself from passive cables or adapters by its active limiting function. The product line focuses on safeguarding expensive or sensitive receiver stages from damage due to excessive input power levels.

Replacement Considerations

Consult official manufacturer substitution lists for verified equivalents. Cross-reference technical parameters such as peak power handling, frequency range, and connector type before considering alternative sources. Generic substitutes may not match the specific PIN-Schottky performance characteristics or recovery times documented for this model.
