CP0805B1747CWTR

RF Directional Couplers Overview

The CP0805B1747CWTR is an RF directional coupler manufactured by KYOCERA AVX, designed for signal feedback applications. It operates within a frequency range of 1.71 GHz to 1.785 GHz and utilizes a standard coupling coefficient of 17 ± 1 dB. The component supports a maximum power rating of 3 W and features low insertion loss of 0.4 dB. It provides high isolation of -29 dB and a return loss of -22 dB. Housed in a compact 0805 (2012 metric) surface-mount package, this thin-film device is suitable for wireless LAN implementations.

RF Directional Couplers Procurement Notes

Verify RoHS compliance status as documentation indicates non-compliance with specific environmental directives. Confirm lead-free availability if required for your manufacturing process. Check moisture sensitivity level (MSL 1) handling requirements during storage and reflow soldering. Ensure the supplier provides official datasheets matching the exact suffix CWTR for accurate pinout and thermal specifications.

RF Directional Couplers Selection Notes

Select this component when a precise 17 dB coupling factor is required for GSM or similar bands around 1.8 GHz. The 0805 package size is ideal for space-constrained designs. Consider the 3W power limit for high-power transmitter paths. Compare against other CP0805 variants if different coupling values or frequency ranges better suit the specific circuit topology.

RF Directional Couplers Part Context

This part belongs to the CP0805 series of RF directional couplers from KYOCERA AVX. The series offers various coupling coefficients and frequency ranges tailored for wireless communications. These components are engineered for use in mobile phones, base stations, and other RF front-end modules requiring reliable signal sampling and monitoring.

RF Directional Couplers Replacement Considerations

Direct substitutes include other CP0805 series parts with matching 17 dB coupling and 1.7-1.8 GHz frequency range. Verify that alternative manufacturers offer compatible 0805 footprints and similar electrical parameters such as insertion loss and isolation levels.
