CP0805B1747BSTR

RF Directional Couplers Overview

The CP0805B1747BSTR is an RF directional coupler manufactured by KYOCERA AVX, designed for wireless LAN applications. It operates within a frequency range of 1.7 GHz to 1.784 GHz. The component features a coupling coefficient of 17 ± 1 dB and supports a maximum power handling of 3 W. It exhibits an insertion loss of 0.4 dB, isolation of -29 dB, and return loss of -22 dB. The device is housed in a compact 0805 (2012 Metric) surface-mount package.

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 with high isolation capabilities to minimize interference between coupled ports

RF Directional Couplers Applications

• Wireless LAN systems operating in the 1.7 GHz band
• RF signal monitoring and measurement circuits
• Power detection and feedback control loops in communication modules

RF Directional Couplers Procurement Notes

Verify that the specific part number matches the required frequency range and coupling coefficient for your design. Confirm compliance with RoHS3 standards and check the moisture sensitivity level before assembly. Ensure the 0805 footprint aligns with your PCB layout guidelines. Cross-reference the datasheet for thermal and power derating requirements under actual operating conditions.

RF Directional Couplers Selection Notes

Select this component when a 17 dB coupling factor is required for signals near 1.7 GHz. The 0805 package offers a balance between size and power handling for 3 W applications. Consider the -29 dB isolation specification if port-to-port interference is a critical design constraint. Compare against other series if different coupling values or frequency bands are needed.

RF Directional Couplers Part Context

This component belongs to the CP0805 series of SMD type RF directional couplers from KYOCERA AVX. These devices are part of a broader portfolio of passive components designed for high-frequency applications. The series utilizes advanced ceramic technology to ensure stability and reliability in compact form factors suitable for modern electronic equipment.

RF Directional Couplers Replacement Considerations

Check for direct substitutes within the CP0805 series that offer similar coupling coefficients and frequency ranges. Verify that any alternative component maintains the same 0805 footprint and pin configuration to ensure compatibility with existing PCB layouts without redesign.
