CP30008A-20

RF Directional Couplers Overview

The CP30008A-20 is a broadband dual directional coupler manufactured by Amtery Corporation, designed for RF applications within the 500 MHz to 8 GHz frequency range. It features a nominal coupling factor of 20 dB and supports up to 20 W of power handling capacity. The device utilizes SMA female connectors for interface connectivity. Typical directivity is specified at 26 dB, with a minimum directivity of 22 dB, ensuring effective signal separation in bidirectional measurement scenarios.

RF Directional Couplers Feature Summary

• Dual directional coupling architecture for simultaneous forward and reverse signal monitoring
• Broadband operational capability spanning from 500 MHz to 8 GHz
• High power handling rated for 20 W continuous wave operation
• Integrated SMA female connectors for standardized RF interconnection

RF Directional Couplers Applications

• RF signal monitoring in communication systems
• Bidirectional power measurement setups
• Transmitter output and reflected power analysis
• Test and measurement instrumentation front-ends

RF Directional Couplers Procurement Notes

Verify the specific datasheet version (CP30008A-20(1).pdf or CP30008A-20(2).pdf) against your design requirements before ordering. Confirm that the SMA female connector type matches your cable assembly specifications. Ensure the 20 W power rating aligns with your system's peak and average power levels. Check for any manufacturing lot variations that might affect directivity performance near the 22 dB minimum threshold.

RF Directional Couplers Selection Notes

Select this component when a wide bandwidth covering sub-GHz to microwave frequencies is required. The 20 dB coupling factor provides a balanced trade-off between signal sampling strength and insertion loss. Consider the 20 W power limit if operating high-power transmitters. The dual-directional nature makes it suitable where both incident and reflected waves must be measured simultaneously using separate ports.

RF Directional Couplers Part Context

Amtery Corporation specializes in designing and manufacturing high-performance RF components. The CP30008A-20 belongs to their module series featuring SMA connectors. This part is distinct from other Amtery couplers like the CP10008A-20 (6 dB coupling) or CP10710P150-20, which serve different coupling factors or frequency ranges within the same product family.

RF Directional Couplers Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Direct replacements require matching the 500 MHz–8 GHz bandwidth, 20 dB coupling, 20 W power rating, and SMA female interface characteristics.
