Procurement Notes

Verify the specific part number suffix against official L3Harris or Narda-MITEQ documentation to confirm exact electrical tolerances and connector types. Ensure that the ordering information matches the required frequency range and power specifications for your specific design implementation. Cross-reference datasheet revisions to confirm compliance with current environmental standards and package configurations before finalizing procurement orders.

Selection Notes

Select this component when a broad bandwidth covering 100 MHz to 6 GHz is required alongside moderate noise performance. The 40 dB gain and 25 dBm P1dB output make it suitable for intermediate stage amplification in complex receiver chains. Consider the +15 VDC supply requirement and 350 mA current draw during power budgeting. Evaluate thermal management needs given the operational temperature range and module form factor for your enclosure design.

Part Context

This model belongs to the standardized LNA product family from Narda-MITEQ, now part of L3Harris. These amplifiers are engineered for reliability in commercial and military-grade environments. The series typically offers modular designs with SMA interfaces, facilitating straightforward integration into existing RF infrastructure. This specific variant targets applications requiring wideband coverage without excessive noise degradation.

Replacement Considerations

Direct substitutes must match the 100 MHz–6 GHz frequency range, 40 dB gain, and 25 dBm P1dB output. Verify compatibility with +15 VDC supply and 50 Ω interface requirements. Alternative models from the same manufacturer may offer different noise figures or power levels but must maintain equivalent pinout and mechanical dimensions for drop-in replacement.
