RF Directional Couplers Procurement Notes

Verify the specific datasheet version when sourcing, as the component status is listed as obsolete. Confirm that the 0402 package dimensions match your PCB layout requirements. Ensure compatibility with standard SMT reflow processes. Check for RoHS3 compliance documentation if required by your supply chain regulations. Validate the coupling factor tolerance against your system design margins before finalizing procurement.

RF Directional Couplers Selection Notes

Select this component for applications requiring precise directional coupling in the 1.7 to 2.0 GHz range. The 0402 package is suitable for space-constrained designs. Consider the 21.2 dB coupling factor for appropriate signal sampling levels. LTCC technology offers reliability for RF environments. Evaluate the obsolete status for long-term production planning.

RF Directional Couplers Part Context

This part belongs to TDK's family of multilayer chip directional couplers. These components are engineered for RF and microwave applications where size and performance are critical. The HHM2910E4 utilizes Thin Film Technology (LTCC) to achieve consistent electrical characteristics across the specified frequency bands.

RF Directional Couplers Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete lifecycle status, alternative sourcing may require checking distributor inventories or evaluating equivalent components from other manufacturers with similar frequency and package specifications.
