DAT-31A-SP+

Attenuators Overview

The DAT-31A-SP+ is a surface-mount digital step attenuator manufactured by Mini-Circuits. It provides a total attenuation range of 31 dB with a resolution of 1 dB per step. The device operates over a frequency range from DC to 4000 MHz and features a nominal impedance of 50 Ohms. It supports an input power level of +24 dBm and is housed in a 20-VFQFN exposed pad package.

Attenuators Feature Summary

• Digital control interface for precise attenuation steps
• Surface-mount technology for compact integration
• Wideband operation covering DC to 4 GHz

Attenuators Applications

• RF signal path management
• Test and measurement equipment
• Wireless infrastructure systems

Attenuators Procurement Notes

Verify the specific suffix 'SP+' against the manufacturer's current datasheet to confirm pinout compatibility and package dimensions. Ensure that the required attenuation steps align with the 1 dB resolution capability documented for this model before finalizing procurement specifications.

Attenuators Selection Notes

Select this component when a fixed 31 dB attenuation value is required within the specified frequency band. Consider the 50 Ohm impedance match for system integration. Evaluate the thermal performance relative to the +24 dBm power handling limit during high-power signal conditions.

Attenuators Part Context

This part belongs to the Mini-Circuits digital step attenuator family, designed for replacing traditional PIN diode or mechanical switch-based solutions. It offers improved reliability and lower insertion loss compared to discrete switching networks while maintaining a small form factor suitable for modern PCB layouts.

Attenuators Replacement Considerations

The DAT-31A+ is identified as functionally equivalent to the DAT-31A-SP+ according to public replacement guides. Verify package compatibility when substituting.
