CP0805A0942AWTR

RF Directional Couplers Overview

The CP0805A0942AWTR is an RF directional coupler manufactured by KYOCERA AVX, designed for signal monitoring and feedback applications. It operates within a frequency range of 925MHz to 960MHz, covering the E-GSM band. The component features a coupling coefficient of 20.5 ± 1dB and supports a maximum power rating of 3W. Key electrical specifications include an insertion loss of 0.25dB and a return loss of -23dB. It is housed in a compact 0805 (2012 metric) surface-mount package, suitable for space-constrained wireless device designs.

RF Directional Couplers Procurement Notes

Verify RoHS compliance status prior to procurement, as documentation indicates this specific variant may not meet current environmental standards. Confirm that the 0805 package dimensions align with your PCB footprint requirements. Ensure the 3W power handling capacity is sufficient for your application's peak signal levels. Check for availability constraints and standard lead times associated with manufacturer distribution channels.

RF Directional Couplers Selection Notes

Select this component when operating specifically within the 925-960MHz E-GSM frequency range. The 20.5dB coupling value is fixed; ensure it matches your system's required sampling ratio. Consider the 0.25dB insertion loss impact on overall link budget. Verify that the 0805 package size fits your board space limitations compared to larger or smaller alternatives.

RF Directional Couplers Part Context

This part belongs to the CP0805 series of thin-film directional couplers from KYOCERA AVX. These components are engineered for RF and microwave applications requiring stable performance across defined bandwidths. The series utilizes advanced thin-film technology to achieve consistent coupling accuracy and low loss characteristics in miniature surface-mount packages.

RF Directional Couplers Replacement Considerations

Direct substitutes within the same series include CP0805B0942AWTR, which shares similar frequency and package attributes but may differ in coupling coefficients. Cross-reference datasheets for exact electrical parameter matching before substitution.
