Procurement Notes

Verify RoHS compliance status prior to procurement, as documentation indicates this specific part may be non-compliant. Confirm that the connectorized package aligns with your assembly requirements. Ensure the 8-18 GHz frequency range matches your system's operational needs. Validate that the 2.3 dB insertion loss and 2.0:1 VSWR are acceptable for your link budget. Cross-reference the datasheet to confirm the exact physical dimensions and mounting style.

Selection Notes

Select this component when a passive, solid-state solution is required for broadband receiver protection between 8 and 18 GHz. Consider the 2.3 dB insertion loss impact on system sensitivity. Evaluate the 2.0:1 VSWR against impedance matching requirements. Choose this model if octave coverage is necessary without active power sources. Compare against other 2690 Series variants if different frequency ranges or performance metrics are needed.

Part Context

The 2690-1011 belongs to the 2690 Series of coaxial limiters manufactured by MACOM Technology Solutions. This series provides standard limiter solutions for frequencies up to 18 GHz. These components are categorized under RF misc ICs and modules. They serve as passive protectors for sensitive downstream electronics in high-frequency applications.

Replacement Considerations

Consult official MACOM documentation for confirmed substitute part numbers within the 2690 Series. Verify frequency range compatibility, specifically ensuring the replacement covers the 8-18 GHz band. Check insertion loss and VSWR specifications to ensure equivalent performance. Confirm mechanical connector compatibility before substitution.
