Procurement Notes

Verify the specific datasheet version and environmental rating before integration. Confirm that the 13-SMD module footprint matches your PCB layout constraints. Ensure compatibility with standard reflow soldering profiles for SMT components. Cross-reference the part number with official Mini-Circuits documentation to confirm active status and current specifications.

Selection Notes

Select this component when a 50 Ohm system requires a 220 MHz bandwidth centered at 1.28 GHz. Consider the 2 dB insertion loss impact on system noise figure. Evaluate the physical dimensions against available board space. Verify that the ceramic-coaxial construction meets the thermal and mechanical requirements of the target environment.

Part Context
