• Compact 0603 surface-mount footprint facilitates automated PCB assembly

RF Directional Couplers Applications

• RF signal monitoring and measurement systems
• Transmitter output power monitoring
• Receiver input signal level detection
• Bidirectional RF power analysis circuits

RF Directional Couplers Procurement Notes

Verify compliance requirements prior to ordering, as this specific part number is identified as not RoHS compliant. Confirm that the 0603 package dimensions align with the target PCB layout constraints. Ensure the 3W maximum power rating is sufficient for the intended application environment to prevent component failure. Check availability status through authorized distributors, as lead times may vary based on manufacturer production schedules.

RF Directional Couplers Selection Notes

Select this component when a fixed 9.5 dB coupling factor is required for the 1.71-1.785 GHz frequency range. The 0.8 dB insertion loss makes it suitable for low-loss signal path integration. Consider the non-RoHS status if environmental regulations prohibit its use. The 3W power rating defines the upper limit for continuous wave operation. Compare against other CP0603 series variants if different coupling values or frequency bands are needed.

RF Directional Couplers Part Context

This device belongs to the CP0603 series of RF directional couplers from KYOCERA AVX. These components are specialized passive devices used in microwave and radio frequency circuits. The series offers various coupling coefficients and frequency ranges tailored for different communication standards. The CP0603A1747CNTR specifically targets applications requiring stable performance in the lower L-Band or ISM band regions.

RF Directional Couplers Replacement Considerations

Direct substitutes within the same series include CP0603A1747CLTR, which shares identical electrical specifications but differs in packaging configuration. Other models such as CP0603A1250CNTR offer similar form factors but operate at different center frequencies. Verify that any replacement maintains the required 9.5 dB coupling and 1.71-1.785 GHz operational range.
