CP0402A2442FNTR

RF Directional Couplers Overview

The CP0402A2442FNTR is an RF directional coupler designed for Wireless LAN applications operating within the 2.4GHz to 2.484GHz frequency range. Manufactured by KYOCERA AVX, this component utilizes a standard coupler type housed in a compact 0402 (1005 metric) surface-mount package. Key electrical specifications include a coupling coefficient of 22dB and a maximum power rating of 3W. The device exhibits an insertion loss of 0.25dB, providing efficient signal transmission. Additional performance metrics feature an isolation of -33dB and a return loss of 22.6dB, ensuring effective signal monitoring and minimal reflection in high-frequency circuits.

RF Directional Couplers Feature Summary

• Provides flat coupling characteristics across the designated wide frequency band
• Features high directivity for accurate signal separation
• Utilizes low-profile thin-film construction suitable for space-constrained designs

RF Directional Couplers Applications

• Wireless LAN systems
• RF signal monitoring circuits
• Transmitter power measurement

RF Directional Couplers Procurement Notes

Verify that the specific suffix FNTR corresponds to the required tape and reel packaging configuration for automated assembly processes. Confirm that the component's non-RoHS status aligns with environmental compliance requirements for the target market. Ensure that the 0402 footprint matches the PCB layout design rules and soldering capabilities available in the manufacturing facility.

RF Directional Couplers Selection Notes

Select this component when a precise 22dB coupling ratio is required for 2.4GHz ISM band operations. The 3W power handling capability supports moderate power levels typical in wireless transmitters. Consider the 0.25dB insertion loss impact on overall link budget efficiency. Evaluate the -33dB isolation level against system crosstalk requirements to ensure adequate signal purity and directionality performance.

RF Directional Couplers Part Context

This part belongs to the CP0402 series of wideband RF directional couplers from KYOCERA AVX. These components are engineered using thin-film technology to deliver consistent performance across broad frequency ranges. The series is characterized by its small form factor and reliability, making it suitable for integration into modern mobile and wireless communication devices requiring precise RF signal management.

RF Directional Couplers Replacement Considerations

Cross-reference other models within the CP0402A2442 family, such as ELTR variants, which may offer different coupling coefficients like 18dB while maintaining similar physical dimensions and frequency ranges.
