RF Directional Couplers Procurement Notes

Verify compliance with RoHS non-compliant status and REACH regulations prior to procurement. Confirm MSL level 1 classification for moisture sensitivity handling during storage and reflow soldering processes. Ensure ECCN EAR99 export classification aligns with regional trade requirements. Validate that the 0603 package dimensions match the target PCB footprint constraints.

RF Directional Couplers Selection Notes

Select this component when a 9.5dB coupling factor is required for frequencies between 1.71GHz and 1.785GHz. Consider the 3W power limit and -34dB isolation performance for system linearity requirements. The 0603 package size is critical for space-constrained designs. Compare against similar models like CP0603A1747CLTR if different coupling or tolerance specifications are needed.
