Procurement Notes

Verify the specific datasheet version from L3Harris or authorized distributors to confirm current manufacturing status and environmental compliance details. Ensure that the SMA connector orientation and pinout match the system interface requirements. Cross-reference the part number against official L3 Narda-MITEQ catalogs to avoid counterfeit components. Confirm voltage supply specifications align with the design constraints before procurement.

Selection Notes

Select this component when a wide bandwidth covering L through K bands is required alongside moderate noise performance. The 20 dBm output capability suits applications needing substantial drive levels without external buffering. Consider the module form factor for rapid prototyping or space-constrained designs where discrete solutions are impractical. Evaluate thermal management needs based on the continuous operation environment.

Part Context

This model belongs to the LNA-20 series from L3 Narda-MITEQ, which focuses on broadband low-noise amplification. The series typically offers various noise figure options and frequency ranges tailored for different RF subsystems. This specific variant targets the 100 MHz to 18 GHz span, balancing gain flatness and noise characteristics for versatile microwave applications.

Replacement Considerations

Consult official L3 Narda-MITEQ documentation for direct cross-references. Similar broadband LNAs from other manufacturers may require impedance re-matching. Verify if alternative parts offer comparable P1dB and noise figures for equivalent system performance.
