D150NA30C4

Attenuators Overview

The D150NA30C4 is a high-performance fixed RF attenuator manufactured by TTM Technologies, Inc. It utilizes an Aluminum Nitride (AlN) substrate for superior thermal management and mechanical stability. The component operates within a frequency range of DC to 4.6 GHz. It provides a nominal attenuation value of 30 dB with a typical insertion loss of 16 dB. The device supports a continuous power rating of 150 Watts, making it suitable for high-power applications. It features a surface mount (SMD/SMT) mounting style and maintains a standard impedance of 50 Ohms. The part is classified as active with unlimited moisture sensitivity.

Attenuators Feature Summary

• High-power handling capability of 150 Watts using Aluminum Nitride construction
• Broadband operation from DC to 4.6 GHz
• Surface mount design for automated assembly integration

Attenuators Applications

Attenuators Procurement Notes

Verify the specific datasheet version when ordering, as manufacturer specifications may be updated. Confirm that the 150W power rating aligns with your system's thermal dissipation requirements. Ensure PCB layout supports the SMD footprint dimensions provided in the official documentation. Check for any recent changes in RoHS compliance status or packaging configurations directly from TTM Technologies before finalizing procurement.

Attenuators Selection Notes

Select this component when high power handling and wide bandwidth are critical. The AlN substrate offers better thermal conductivity than ceramic alternatives. Consider the 150W rating against peak and average power levels in your circuit. The SMD form factor aids in space-constrained designs. Verify impedance matching at 50 Ohms for optimal performance in standard RF environments.

Attenuators Part Context

This part belongs to the D150 series of fixed attenuators from TTM Technologies' Anaren division. It is designed as a cost-competitive alternative to standard attenuators while maintaining high performance. The series includes various attenuation values and power ratings, all sharing the robust AlN construction. This specific model targets applications needing reliable high-power attenuation in a compact surface-mount package.

Attenuators Replacement Considerations

Direct substitutes include other 30dB 150W AlN SMD attenuators from TTM such as the B150NA30X4. Verify pinout compatibility and thermal pad requirements when swapping parts. Ensure replacement components meet the same 4.6 GHz frequency limit and 50 Ohm impedance standards.
