ZFLM-252-1WL-S+

Overview

The ZFLM-252-1WL-S+ is a broadband RF limiter manufactured by Mini-Circuits, designed to protect sensitive downstream components from high-power signals. It operates within a frequency range of 100 MHz to 2.5 GHz and features SMA connectors for input and output connections. The device utilizes a compact H16 chassis mount case style, ensuring reliable performance in various RF environments. Key electrical specifications include a maximum input power handling capability of 30 dBm and an output power limit of 0 dBm, maintaining a standard 50 Ω impedance throughout the operating band.

Feature Summary

• Provides broadband signal limiting across the 100 MHz to 2.5 GHz frequency spectrum
• Maintains a stable 0 dBm output power level regardless of higher input levels
• Features robust SMA connector interfaces for straightforward integration into coaxial systems

Applications

• Protection of low-noise amplifiers in receiver front-ends
• Signal conditioning in wireless communication infrastructure
• Test and measurement equipment requiring input protection

Procurement Notes

Verify the specific datasheet version when ordering, as manufacturer documentation may undergo revisions. Confirm that the SMA connector gender matches your system requirements, as visual representations in catalogs may vary. Ensure the H16 chassis mounting style is compatible with your enclosure design before finalizing procurement decisions.

Selection Notes

Select this component when a wideband limiting solution is required between 100 MHz and 2.5 GHz. It is suitable for applications needing to clamp input signals to 0 dBm while handling up to 30 dBm input power. Consider the chassis mount form factor if surface-mount options are not feasible for your assembly process.
