Procurement Notes

Verify the exact part number suffix against official L3 Narda-MITEQ documentation to ensure correct pinout and connector configuration. Confirm that the 15V DC supply requirement matches your system power architecture. Check for RoHS compliance status if required by your manufacturing standards. Ensure SMA connector compatibility with your PCB layout or cable assembly specifications before finalizing procurement.

Selection Notes

Select this component when operating frequencies fall between 18 GHz and 40 GHz. It is suitable for applications requiring moderate gain and low noise figures in satellite communications. Consider the 15V supply constraint during power budgeting. Compare performance metrics against alternative modules if higher output power or different frequency ranges are needed for specific link budgets.

Part Context

This model belongs to the LNA series from L3 Narda-MITEQ, focusing on microwave frequency amplification. The naming convention typically indicates series, frequency bands, and performance characteristics. It serves as a critical component in high-frequency signal processing chains where signal integrity and low noise are paramount for reliable data transmission in satellite environments.

Replacement Considerations

Consult official L3 Narda-MITEQ cross-reference lists for verified substitutes. Ensure any replacement maintains the 18-40 GHz frequency range and compatible SMA interface. Verify that electrical parameters such as gain and noise figure meet or exceed original specifications without altering system impedance matching.
