FMMT1021

Overview

The FMMT1021 is a signal conditioning high power limiter manufactured by Fairview Microwave. It operates within a frequency range of 2 GHz to 8 GHz and features SMA connectors. The device supports a continuous wave input power of 1 W (30 dBm) and handles a peak power of 100 W. It exhibits a flat leakage of 16 dBm (0.04 W) and has a recovery time of 20 ns. This component is designed for robust RF signal protection in demanding applications.

Feature Summary

• Provides high power limiting capability with a 100 W peak power rating
• Maintains low flat leakage at 16 dBm across the operating band
• Features rapid 20 ns recovery time for efficient signal processing

Applications

• RF signal conditioning systems requiring power protection
• High-power radar receiver front-ends
• Test and measurement equipment safeguarding sensitive components

Procurement Notes

Verify the specific SMA connector gender and interface type against the official datasheet before integration, as variations may exist. Confirm that the 20 ns recovery time meets the system's temporal requirements. Ensure the 16 dBm leakage level is acceptable for the downstream circuitry sensitivity. Check current availability status through authorized distributors, as supply conditions can change rapidly.

Selection Notes

Select this limiter when a wide bandwidth from 2 GHz to 8 GHz is required alongside high peak power handling. It is suitable for applications needing fast recovery after power events. Consider the 16 dBm leakage specification to ensure it does not overload subsequent stages. Verify compatibility with existing SMA infrastructure in the design.

Part Context

This component belongs to the Fairview Microwave signal conditioning portfolio, specifically designed for RF limiters. It addresses the need for protecting sensitive receivers from high-power signals while maintaining signal integrity over a broad microwave frequency range. The module integrates directly into RF chains via standard connectors.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Evaluate alternatives based on matching frequency range, peak power rating, and leakage specifications.
