RF Directional Couplers Procurement Notes

Verify RoHS compliance status carefully, as documentation indicates conflicting information regarding RoHS3 specification adherence for this specific part number. Confirm the manufacturer's current environmental declaration before integration. Ensure the ordering suffix matches the required packaging configuration. Validate that the component meets all relevant regulatory standards for the intended deployment region.

RF Directional Couplers Selection Notes

Select this component when operating within the 824MHz to 849MHz band requires high isolation and low insertion loss. The 0402 package size is ideal for space-constrained designs. Consider the 3W power limit for system power budgeting. Evaluate the 22dB coupling factor against system sensitivity requirements to ensure adequate signal sampling without excessive attenuation.
