Procurement Notes

Verify the specific suffix configuration against official documentation to confirm functional equivalence, as ordering suffixes may indicate variations in packaging or tape-and-reel specifications rather than electrical changes. Confirm availability status through authorized channels, as supply constraints may affect immediate fulfillment. Ensure compatibility with existing PCB footprints and reflow profiles before integration.

Selection Notes

Select this component when a 28 GHz center frequency and 3 GHz bandwidth are required for microwave signal processing. The 50 Ohm impedance matches standard RF transmission lines. Consider the -55°C to +125°C operating range for harsh environments. Verify that the surface-mount form factor aligns with assembly capabilities and spatial constraints within the target application design.
