RF Directional Couplers Procurement Notes

Verify the specific suffix 'ENTR' against official manufacturer documentation to confirm exact electrical tolerances and packaging specifications. Ensure compatibility with RoHS compliance requirements if mandated by project standards. Confirm that the 0603 footprint aligns with existing PCB layout constraints before finalizing procurement orders.

RF Directional Couplers Selection Notes

Select this component when a 9.5dB coupling factor is required for the 1.7GHz band. Consider the 0603 package size for space-constrained designs. Evaluate the 3W power rating against system peak power levels. Compare isolation performance against alternative models if strict port separation is critical for the application architecture.
