RF Directional Couplers Procurement Notes

Verify the specific suffix 'CWTR' against official datasheets to confirm the exact coupling tolerance and frequency band variant, as ordering suffixes may denote distinct electrical parameters or packaging configurations. Ensure compatibility with RoHS compliance requirements if mandated by the end product, noting that some variants in this series may not meet current environmental standards. Cross-reference the manufacturer's latest documentation to confirm availability and lead times prior to finalizing procurement plans.

RF Directional Couplers Selection Notes

Select this component when a 20 dB coupling factor is required for the 1.8 GHz GSM/UMTS band range. The 0603 package size is suitable for space-constrained mobile devices and base stations. Consider the 3W power handling capability relative to the system's maximum transmit power. Evaluate the -36 dB isolation specification to ensure adequate signal separation for the intended application architecture.
