Procurement Notes

Verify the specific datasheet version when sourcing, as Mini-Circuits may update documentation over time. Confirm that the NL1008C-7 package matches your PCB footprint requirements. Ensure the operating environment aligns with the component's specified temperature range. Cross-reference the 50 Ohm impedance with your system design to prevent mismatch issues. Check for any recent revisions in the official Mini-Circuits catalog before finalizing procurement.

Selection Notes

Select this component when a narrow bandpass response around 18.95 GHz is required. The LTCC construction offers stability compared to other ceramic types. Consider the 1.4 to 3 dB insertion loss impact on system gain. The SMD package facilitates automated assembly. Verify that the 17.7 to 20.2 GHz passband covers all necessary signal frequencies without excessive attenuation outside the desired range.
