RF Directional Couplers Procurement Notes

Verify the specific suffix 'BWTR' against the manufacturer's current datasheet to confirm packaging and tape specifications. Ensure the procurement channel sources components directly from authorized distributors or the manufacturer to guarantee authenticity. Confirm that the RoHS status aligns with project requirements, as this specific part number may differ from other variants in the series regarding compliance standards.

RF Directional Couplers Selection Notes

Select this component when a precise 10 dB coupling ratio is required at the 1.441 GHz frequency point. The 3W power handling capability makes it suitable for moderate power levels typical in wireless LAN infrastructure. Consider the 0.9 dB insertion loss impact on overall system gain. Compare against higher directivity alternatives if signal isolation accuracy is critical for the specific application environment.
