CP20018A-20

RF Directional Couplers Overview

The Amtery Corporation CP20018A-20 is a bidirectional RF directional coupler module designed for high-frequency applications. It operates within a frequency range of 500 MHz to 18 GHz and provides a nominal coupling factor of 20 dB. The component features SMA female connectors for interface connectivity. Key electrical specifications include an insertion loss of 1.7 dB, an isolation rating of 42 dB, and a return loss of 21 dB. This module supports power levels up to 20 W, making it suitable for signal monitoring tasks in wideband radio frequency systems.

RF Directional Couplers Feature Summary

• Bidirectional coupling capability for simultaneous forward and reverse signal measurement
• Wide operational bandwidth spanning from 500 MHz to 18 GHz
• High isolation performance ensuring minimal signal leakage between ports

RF Directional Couplers Applications

• RF signal monitoring in communication systems

RF Directional Couplers Procurement Notes

Verify the specific connector type and pin configuration against system requirements before procurement. Confirm that the operating frequency range aligns with the intended application spectrum. Ensure the power handling capacity meets the maximum expected signal levels to prevent component damage. Check for any specific environmental ratings if deployment occurs in non-standard conditions.

RF Directional Couplers Selection Notes

Select this component when bidirectional monitoring is required across a broad microwave frequency range. The 20 dB coupling factor offers a balanced trade-off between signal sampling strength and main line attenuation. Consider the SMA interface compatibility with existing cabling infrastructure. Evaluate the 42 dB isolation specification to ensure adequate port separation for the specific circuit topology.

RF Directional Couplers Part Context

This part belongs to Amtery Corporation's series of high-performance RF components. It is categorized as a general-purpose directional coupler module. The product line includes variants with different coupling factors and frequency ranges, such as the CP20118A-20. These modules are engineered for integration into larger RF subsystems requiring precise signal characterization.

RF Directional Couplers Replacement Considerations

Direct substitutes may include other bidirectional couplers with similar 20 dB coupling and 18 GHz upper frequency limits. Verify mechanical dimensions and SMA connector gender compatibility during replacement. Cross-reference isolation and insertion loss specifications to maintain system performance integrity.
