RF Directional Couplers Procurement Notes

Verify the specific suffix '500' against official KYOCERA AVX documentation to confirm reel quantity or variant specifics, as standard listings often reference 'AWTR'. Ensure compatibility with 869-894 MHz design requirements. Confirm RoHS status if required, as some sources indicate non-compliance for this series. Cross-reference datasheet revision dates for accurate parameter validation.

RF Directional Couplers Selection Notes

Select this component for designs requiring fixed coupling ratios in the AMPS band. Consider the 0805 footprint constraints and 3W power handling limits. Evaluate thermal performance under continuous operation. Compare alternative couplers if different coupling coefficients or frequency ranges are needed. Verify impedance matching requirements for the target application circuit.
