CP0603A0942ELTR

RF Directional Couplers Overview

The CP0603A0942ELTR is a thin film directional coupler manufactured by KYOCERA AVX, designed for RF signal conditioning applications. It operates within a frequency range of 942 MHz and features a standard coupling coefficient of 42 dB. The component supports a maximum power handling capacity of 3 W and maintains a 50 Ohm impedance. Packaged in a compact 0603 (1608 metric) surface-mount footprint, it offers high directivity suitable for precise signal monitoring. The device is supplied in tape and reel packaging to facilitate automated assembly processes.

RF Directional Couplers Feature Summary

• Thin film construction ensures stable performance across the operating frequency band
• High directivity provides accurate signal separation and monitoring capabilities
• Compact 0603 surface-mount package enables efficient PCB space utilization

RF Directional Couplers Applications

• RF signal monitoring in communication systems
• Power measurement circuits
• Signal integrity testing equipment

RF Directional Couplers Procurement Notes

Verify the specific suffix and packaging configuration when ordering, as availability may vary between tape and reel or cut tape options. Confirm that the 3 W power rating aligns with your system's peak power requirements. Ensure the 0603 footprint matches your board layout constraints. Check for any RoHS compliance status updates if required by your project specifications.

RF Directional Couplers Selection Notes

Select this component when a 42 dB coupling factor is required for low-level signal sampling at 942 MHz. The 0603 size is appropriate for dense layouts where larger packages are not feasible. Consider the 3 W power limit to ensure reliability under continuous operation. Compare insertion loss and isolation specs against other models in the CP0603 series if higher directivity is needed.

RF Directional Couplers Part Context

This part belongs to the CP0603 series of high-directivity thin film directional couplers from KYOCERA AVX. The series covers various frequency bands and coupling factors, all sharing the same 0603 form factor. This model specifically targets the 942 MHz band, distinguishing it from other variants like the CP0603A0880CLTR which operates at 880 MHz.

RF Directional Couplers Replacement Considerations

Direct substitutes within the same series include parts with similar coupling factors and frequencies, such as the CP0603A0902ELTR for 902 MHz applications. Verify electrical parameters closely, as coupling factor variations significantly impact circuit performance. Cross-reference pinout and thermal characteristics to ensure compatibility.
