3000-30

Overview

The L3 Narda-MITEQ 3000-30 is a precision coaxial directional coupler designed for RF applications within the 225 to 460 MHz frequency range. It provides a nominal coupling factor of 30 dB with a coupling variation of ±1.2 dB and directivity of 30 dB. The component supports high power handling capabilities typical of its series, ensuring reliable signal sampling and monitoring in test and measurement environments.

Feature Summary

• Provides precise signal sampling via fixed 30 dB coupling factor
• Maintains high directivity for accurate forward and reverse power separation
• Operates reliably across UHF frequency bands from 225 to 460 MHz

Applications

• RF signal monitoring and sampling in communication systems
• Forward and reflected power measurement setups
• Antenna tuning and impedance matching verification
• Test and measurement instrumentation input stages

Procurement Notes

Verify the specific connector type and cable assembly requirements against your system interface before ordering. Confirm that the operating frequency range aligns strictly with the 225–460 MHz specification. Ensure environmental conditions match the component's rated limits for temperature and humidity during deployment.

Selection Notes

Select this model when a fixed 30 dB coupling ratio is required for UHF band operations. Consider the physical size and mounting constraints relative to your enclosure design. Evaluate the need for high directivity to minimize measurement errors in bidirectional signal paths compared to lower-performance alternatives.

Part Context

This component belongs to the Narda-MITEQ line of passive RF microwave components. It complements other directional couplers and attenuators in their portfolio, serving as a standard solution for engineers requiring stable coupling characteristics without active amplification or complex tuning mechanisms.

Replacement Considerations

Check for exact coupling value matches (30 dB) and frequency overlap (225-460 MHz). Verify connector compatibility and power handling ratings. Consult manufacturer cross-reference guides for equivalent models with identical electrical performance specifications.
