PE8033

Overview

The Pasternack PE8033 is a high-power RF limiter designed for signal protection in microwave systems. It utilizes SMA connectors and operates across a frequency range of 2 GHz to 18 GHz. The device handles a peak power of 100 Watts with a typical insertion loss of 2.5 dB. It features a recovery time of 200 microseconds and maintains flat leakage at 18 dBm. The unit supports an operational temperature range from -55°C to 90°C.

Feature Summary

• PIN-Schottky limiting technology for robust signal protection
• High peak power handling capability up to 100 Watts
• Broadband operation spanning 2 GHz to 18 GHz
• SMA connector interface for standard integration

Applications

• Transmitter output protection

• Test and measurement equipment signal conditioning
• Radar system component protection

Procurement Notes

Verify the specific datasheet version for exact electrical tolerances and mechanical dimensions before procurement. Confirm that the SMA connector gender and cable assembly requirements match the system design. Ensure environmental specifications meet the deployment temperature constraints. Cross-reference part numbers to avoid confusion with similar Pasternack limiter models.

Selection Notes

Select this model when broadband coverage from 2 GHz to 18 GHz is required alongside high peak power handling. Consider the 200 microsecond recovery time for pulse applications. Evaluate the 2.5 dB insertion loss impact on system gain budgets. Verify compatibility with existing SMA infrastructure and thermal management capabilities within the operating range.

Part Context

This component belongs to Pasternack's line of RF limiters, which are passive devices used to protect sensitive downstream electronics from excessive power levels. These limiters typically employ PIN diodes or Schottky barriers to clamp voltage spikes while maintaining signal integrity within safe operating limits for connected components.

Replacement Considerations

Direct substitutes must match the 2-18 GHz frequency range, 100W peak power rating, and SMA interface. Verify equivalent insertion loss and recovery time specifications. Check for compatible mounting styles and thermal characteristics if replacing in an existing assembly.
