Procurement Notes

Verify that the specific ordering suffix matches the required performance characteristics, as variations may exist within the product line. Confirm the active status of the component through official manufacturer channels before finalizing procurement plans. Ensure that the surface-mount footprint aligns with the design constraints of the target printed circuit board layout. Cross-reference the datasheet parameters against system requirements to guarantee compatibility with existing RF infrastructure.

Selection Notes

Select this component when a 1:1.33 impedance transformation is required for frequencies up to 1.3 GHz. Consider the low insertion loss and tight phase difference specifications for high-fidelity signal transmission. Evaluate the surface-mount form factor against available board space and assembly capabilities. Compare the return loss performance against system tolerance levels to ensure minimal signal reflection.
