RF Directional Couplers Procurement Notes

Verify that the specific lot date code aligns with project requirements, as manufacturing batches may vary. Confirm compliance with REACH regulations, noting that this component is not subject to REACH restrictions. Ensure that the 0805 footprint matches the PCB design guidelines. Check for any specific storage conditions required for moisture-sensitive levels prior to soldering.

RF Directional Couplers Selection Notes

Select this component when a standard coupling ratio is required for E-GSM frequencies. The 0805 package offers a balance between size and power handling compared to smaller footprints. Consider the 3W power rating against peak transmitter outputs. Evaluate the 0.25dB insertion loss impact on overall link budget. Compare isolation specifications if multiple coupled ports are needed in the design.
