PE8027

Overview

The Pasternack PE8027 is a coaxial PIN-diode limiter designed for RF applications. It operates within a frequency range of 11 GHz to 18 GHz and features SMA connectors (SMA-F to SMA-M). The device handles a peak power input of 100 Watts with a flat leakage of 16 dBm. It maintains a maximum voltage standing wave ratio (VSWR) of 2.2:1 and has a characteristic impedance of 50 Ω. The unit supports operating temperatures from -55 °C to 125 °C.

Feature Summary

• Provides high peak power handling capability up to 100 Watts.
• Maintains low signal leakage at 16 dBm during limiting events.
• Ensures stable signal transmission with a VSWR of 2.2:1.
• Operates reliably across an extended temperature range.

Applications

• Protecting sensitive receiver front-ends from high-power signals.
• Integration into radar systems requiring signal protection.
• Use in communication equipment operating in the X-band and Ku-band frequencies.

Procurement Notes

Verify the specific connector gender configuration, as datasheets may list SMA-F and SMA-M variations. Confirm that the 100W peak power rating aligns with your system's transient requirements. Ensure the 11-18 GHz frequency coverage matches your operational band. Check RoHS compliance status if required by your manufacturing standards.

Selection Notes

Select this component when a fixed-limiting solution is required for coaxial lines. It is suitable for designs needing robust protection against power surges without active control. Consider the physical size and mounting requirements for integration into existing chassis or test setups.

Part Context

This limiter belongs to Pasternack's line of coaxial packaged RF limiters. It is distinct from their cable assemblies and phase shifters. The product serves as a passive protection device, differing from active amplifiers or tunable filters found in other RF categories.

Replacement Considerations

No public substitute part numbers are confirmed in the provided documentation. Verify compatibility with existing SMA interfaces before considering alternative models.
