3042B-20

Overview

The L3 Narda-MITEQ 3042B-20 is a broadband coaxial directional coupler designed for RF signal monitoring and measurement applications. It operates across a frequency range of 920 MHz to 2.2 GHz, providing a nominal coupling factor of 20 dB. The component features Type N-Female connectors on both the input and output ports, ensuring compatibility with standard coaxial systems. It exhibits a low insertion loss of 0.25 dB, maintaining signal integrity within the passband. This device serves as a passive microwave component suitable for general-purpose wireless communication bands.

Feature Summary

• Directional coupling architecture for forward and reflected power monitoring
• Broadband operation spanning cellular and ISM frequency bands
• Standard Type N-Female connector interface for robust mechanical connection

Applications

• Cellular base station signal monitoring
• ISM band wireless communication system testing
• General purpose RF power measurement setups

Procurement Notes

Verify the specific datasheet revision and connector gender configuration prior to ordering. Confirm that the operating frequency range of 920 MHz to 2.2 GHz aligns with the target application requirements. Ensure that the 20 dB coupling value meets the system's power monitoring sensitivity needs. Check for any specific environmental ratings if the deployment involves extreme conditions. Validate that the Type N-Female interface matches existing cable assemblies.

Selection Notes

Select this model when a fixed 20 dB coupling ratio is required within the 920 MHz to 2.2 GHz spectrum. Consider the Type N-Female interface for compatibility with standard coaxial infrastructure. Evaluate the 0.25 dB insertion loss against system budget constraints. Compare performance metrics against alternative couplers if wider bandwidth or different coupling factors are necessary. Ensure the physical size and mounting style fit the intended enclosure or rack space.

Part Context

The 3042B-20 belongs to the 3042B series of broadband coaxial directional couplers manufactured by L3 Narda-MITEQ. This series is engineered for high-performance microwave and RF applications requiring reliable signal sampling. The product line typically includes various coupling values and frequency ranges to support diverse communication standards. The 3042B-20 specifically targets mid-band frequencies common in modern wireless networks.

Replacement Considerations

Direct substitutes may include other models from the 3042B series with matching coupling factors or frequency ranges. Cross-reference specifications such as VSWR, directivity, and power handling capabilities when evaluating alternatives. Verify connector type consistency to avoid adapter usage. Consult manufacturer documentation for updated part numbers or superseded components.
