CP0402A0881ALTR

RF Directional Couplers Overview

The CP0402A0881ALTR is an RF directional coupler manufactured by KYOCERA AVX, designed for high directivity applications. It operates within a frequency range of 869 MHz to 894 MHz and utilizes a compact 0402 (1005 metric) surface-mount package. The component features a standard coupling type with a specified coupling coefficient of 21 dB. Key electrical parameters include a maximum insertion loss of 0.25 dB, isolation of -46 dB, and a return loss of 27 dB. It supports a maximum power handling capacity of 3 W and is supplied in tape and reel packaging.

RF Directional Couplers Feature Summary

• High directivity design ensures precise signal monitoring and separation within the specified frequency band.
• Compact 0402 surface-mount footprint enables integration into space-constrained mobile and wireless devices.
• Standard coupling configuration provides consistent signal attenuation characteristics for reliable system performance.

RF Directional Couplers Applications

• GSM cellular communication systems
• Mobile phone baseband circuits
• Wireless handset signal monitoring

RF Directional Couplers Procurement Notes

Verify that the ordering suffix matches the required tape and reel packaging format. Confirm compliance with RoHS regulations as the product may not meet current environmental standards. Ensure the supplier provides valid traceability documentation for the manufacturing batch. Check lead times against current production schedules to avoid delays in assembly planning.

RF Directional Couplers Selection Notes

Select this component when a tight coupling factor of 21 dB is required for the 869-894 MHz band. Evaluate the 0402 package size against available board real estate constraints. Consider the 3 W power rating to ensure it exceeds the maximum expected signal levels in the application path without degradation.

RF Directional Couplers Part Context

This part belongs to the CP0402 series of thin-film RF components from KYOCERA AVX. These components are engineered for high-frequency signal conditioning using advanced multilayer thin-film technology.
