RF Directional Couplers Procurement Notes

Verify the specific suffix 'A' against the manufacturer's current datasheet to confirm compliance with RoHS directives, as some variants in this series may not meet these standards. Confirm that the required operating temperature range aligns with the specified -40°C to +85°C limits. Ensure the PCB layout accommodates the 0805 package dimensions and that the system can handle the 3W maximum power rating without degradation.

RF Directional Couplers Selection Notes

Select this component when a precise 20.5 dB coupling factor is required for E-GSM band operations. The low insertion loss of 0.25 dB makes it suitable for applications where signal integrity is critical. Consider the 0805 form factor for space-constrained designs. Verify that the 3W power handling meets the peak power requirements of the specific RF path before finalizing the design.
