RF Directional Couplers Procurement Notes

Verify the specific suffix 'DWTR' against official KYOCERA AVX documentation to confirm exact packaging and material specifications. Ensure compatibility with 0805 footprint requirements during PCB layout. Confirm RoHS compliance status as indicated in manufacturer datasheets, noting potential regulatory differences compared to lead-free variants.

RF Directional Couplers Selection Notes

Select this component when designing for GSM frequencies between 890MHz and 915MHz requiring a 0805 form factor. Consider the 3W power rating and 12.5dB coupling value for appropriate signal attenuation needs. Evaluate the -19dB isolation level against system interference requirements. Compare against other CP series variants if different coupling ratios or frequency bands are necessary.
