CP0805A0947BWTR

RF Directional Couplers Overview

The CP0805A0947BWTR is an RF directional coupler manufactured by KYOCERA AVX, designed for GSM applications within the 890MHz to 915MHz frequency range. It features a standard coupling coefficient of 12.5 ± 1dB and supports a maximum power rating of 3W. The component exhibits an insertion loss of 0.5dB, isolation of -19dB, and return loss of -23dB. Packaged in a compact 0805 (2012 metric) surface-mount footprint, it is supplied in tape and reel format with a manufacturer standard delivery time of 14 weeks.

RF Directional Couplers Feature Summary

• Provides precise signal sampling via standard directional coupling architecture
• Optimized for low insertion loss to maintain signal integrity in RF paths
• Engineered for high isolation to minimize interference between coupled ports

RF Directional Couplers Applications

• GSM communication systems
• RF signal monitoring circuits
• Power measurement modules

RF Directional Couplers Procurement Notes

Verify RoHS compliance status as this specific part number is listed as non-compliant in distributor documentation. Confirm the required tape and reel packaging quantity matches production needs. Ensure the 0805 footprint aligns with the target PCB layout. Check for any specific handling requirements related to the surface-mount package type before assembly.

RF Directional Couplers Selection Notes

Select this component when designing for GSM bands requiring a 12.5dB coupling factor. The 3W power rating suits moderate power levels typical in mobile infrastructure. Consider the 0805 size constraint for space-limited designs. Verify that the -19dB isolation meets system noise floor requirements. Compare against other CP0805 variants if different coupling values or frequency ranges are needed.

RF Directional Couplers Part Context

This device belongs to the CP0805 series of SMD RF directional couplers from KYOCERA AVX. These components are engineered for wireless communication modules, offering reliable performance in compact form factors. The series covers various frequency ranges and coupling coefficients to support diverse RF front-end architectures.

RF Directional Couplers Replacement Considerations

Direct substitutes include CP0805A0902DWTR for similar GSM band applications with identical coupling characteristics. Other CP0805 variants may be considered if frequency ranges or coupling values differ slightly.
