CP0603A2442DNTR

RF Directional Couplers Overview

The CP0603A2442DNTR is a thin-film directional coupler manufactured by KYOCERA AVX, designed for signal conditioning applications. It operates within the 2.4 GHz to 2.484 GHz frequency range with a nominal coupling coefficient of 10 dB ± 1 dB. The component features a standard impedance of 50 Ohms and utilizes an SMD/SMT termination type housed in a compact 0603 (1608 metric) package. Key performance metrics include an insertion loss of 0.85 dB, isolation of -21 dB, and return loss of -23 dB. It supports a maximum power handling capacity of 3 W and functions reliably across a temperature range of -40°C to +85°C.

RF Directional Couplers Procurement Notes

Verify the specific suffix DNTR against the official datasheet to confirm package and tape/reel specifications. Ensure compatibility with RoHS3 compliance requirements if mandated by the target application. Cross-reference the manufacturer part number with distributor listings to confirm current availability and lead times prior to finalizing procurement plans.

RF Directional Couplers Selection Notes

Select this component when a precise 10 dB coupling factor is required for signal sampling in 2.4 GHz applications. Consider the 0.85 dB insertion loss impact on system gain budget. Evaluate the 3 W power rating against peak signal levels to prevent thermal degradation. Confirm that the 0603 package dimensions fit within the available board real estate constraints.
