PE8021

Overview

The PE8021 is a high-power limiter manufactured by Pasternack, designed for signal conditioning within RF systems. It utilizes SMA connectors and operates across a frequency range of 2 GHz to 8 GHz. The component features a peak power handling capability of 100 Watts and exhibits a flat leakage specification of 16 dBm. Technical performance includes a recovery time of 20 nanoseconds. This device is engineered to protect sensitive downstream components from excessive input power levels while maintaining signal integrity within the specified operational bandwidth.

Feature Summary

• Provides high-power limiting protection for RF signal paths
• Utilizes SMA connector interface for series integration
• Ensures low flat leakage output during limiting events
• Features rapid recovery time for continuous operation

Applications

• Protection of sensitive receiver front-ends in communication systems
• Signal conditioning in radar transmission chains
• RF test and measurement equipment input stages
• Base station transmitter protection circuits

Procurement Notes

Verify the specific datasheet version and manufacturer documentation to confirm current technical specifications and compliance status. Ensure that the SMA connector gender and mating requirements align with the system design. Cross-reference the operating frequency range and power handling limits against the actual application environment to guarantee reliable performance under peak load conditions.

Selection Notes

Select this component when a broadband limiter covering 2 GHz to 8 GHz is required. Consider the 100W peak power rating and 16 dBm leakage threshold relative to the system's maximum expected input signals. Evaluate the 20 ns recovery time against the pulse repetition frequency of the application to ensure adequate reset capabilities between high-power events without thermal or electrical degradation.

Part Context

The PE8021 belongs to Pasternack's portfolio of RF signal conditioning devices, specifically categorized as high-power limiters. It complements other passive and active RF components such as adapters, cables, and amplifiers within the manufacturer's ecosystem. This part serves as a protective element in RF chains, distinguishing itself from standard attenuators or couplers by its non-linear limiting behavior under high-power stress conditions.
