CP0805A0902DWTR

RF Directional Couplers Overview

The CP0805A0902DWTR is an RF directional coupler manufactured by KYOCERA AVX, designed for GSM applications within the 890MHz to 915MHz frequency range. It features a 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 standard manufacturer lead time of 14 weeks.

RF Directional Couplers Feature Summary

• Provides precise signal sampling via a 12.5dB coupling coefficient for accurate RF monitoring
• Ensures high signal integrity with low insertion loss of 0.5dB and strong isolation capabilities
• Engineered for robust performance in GSM bands with a 3W maximum power handling capacity

RF Directional Couplers Applications

• GSM network infrastructure monitoring
• RF signal feedback loops
• Power measurement systems

RF Directional Couplers Procurement Notes

Verify the specific suffix 'D' against official datasheets to confirm exact coupling tolerance and electrical characteristics, as variations may exist within the series. Confirm RoHS non-compliance status if environmental regulations apply. Check current availability as the item is listed as made-to-order with a 14-week standard delivery period from the manufacturer.

RF Directional Couplers Selection Notes

Select this component when a fixed 12.5dB coupling ratio is required for GSM band signal monitoring. Ensure the 0805 package size fits the PCB layout constraints. Verify that the 3W power rating exceeds the expected operating power levels. Consider the -19dB isolation specification for system noise floor requirements.

RF Directional Couplers Part Context

This part belongs to the KYOCERA AVX CP0805 series of surface-mount RF directional couplers. These components are engineered for wireless communication applications, offering reliable signal coupling in small form factors. The series supports various frequency ranges and coupling values tailored for different RF system architectures.

RF Directional Couplers Replacement Considerations

CP0805B0902AWTR offers similar GSM frequency coverage but differs in coupling coefficient (21dB vs 12.5dB) and insertion loss (0.25dB vs 0.5dB). Verify circuit compatibility before substitution due to significant differences in signal attenuation and coupling ratios.
