Attenuators Procurement Notes

Verify the specific datasheet version from Fairview Microwave or authorized distributors to confirm current manufacturing status and technical specifications. Ensure that the SMA connector gender and cable assembly requirements match your system design before procurement. Cross-reference the 2W power rating against your actual operating conditions to prevent thermal issues. Confirm that the 100 MHz to 3 GHz operational range aligns with your application's frequency needs.

Attenuators Selection Notes

Select this component when a fixed 20 dB attenuation is required within the UHF and lower microwave bands. The 2W power rating makes it suitable for moderate signal levels common in many RF setups. The SMA interface offers widespread compatibility with standard laboratory and industrial RF components. Consider the physical size and inline form factor for space-constrained designs where modular attenuation is necessary.

Attenuators Part Context

This part belongs to Fairview Microwave's line of connectorized attenuators, which are engineered for precision signal control. The FMAT series typically includes various attenuation values and connector types to support diverse RF testing and system integration needs. These components are essential for managing signal strength in sensitive electronic environments.

Attenuators Replacement Considerations

Direct substitutes may include other 20 dB fixed attenuators with SMA connectors and similar power ratings from manufacturers like Mini-Circuits or Pasternack. Verify that any replacement matches the 50 Ohm impedance, 2W power handling, and 100 MHz to 3 GHz frequency range to ensure functional equivalence.
