DAT-31A-PP+

Attenuators Overview

The DAT-31A-PP+ is a 50Ω digital step attenuator from Mini-Circuits, offering an attenuation range of 0 to 31 dB in 1.0 dB steps across a frequency range of 0 Hz to 4 GHz. It features a 5-bit serial/parallel control interface and operates on a supply voltage of 3 V. The component is housed in a 20-VFQFN exposed pad package with surface mount mounting style. It supports a maximum power handling of 0.25 W and functions within a temperature range of -40°C to +85°C.

Attenuators Feature Summary

• Provides precise digital step attenuation with 1.0 dB resolution up to 31 dB
• Operates over a wide frequency range from DC to 4 GHz
• Utilizes a compact 20-VFQFN surface mount package for space-constrained designs

Attenuators Applications

• RF signal path adjustment in wireless infrastructure
• Test and measurement equipment requiring variable attenuation
• Aerospace and defense communication systems

Attenuators Procurement Notes

Verify the specific suffix PP+ against the official Mini-Circuits datasheet to confirm pinout compatibility and package dimensions. Ensure the selected variant matches the required 5-bit control interface and operating voltage specifications for your system design.

Attenuators Selection Notes

Select this component when a 50Ω impedance match is required for frequencies up to 4 GHz. Consider the 20-VFQFN package size for PCB layout constraints and verify that the 3 V logic level aligns with the controlling microcontroller or FPGA outputs.

Attenuators Part Context

This part belongs to the DAT-31A+ series of digital step attenuators manufactured by Mini-Circuits. The series provides adjustable attenuation capabilities suitable for RF and microwave applications where precise signal level control is necessary without introducing significant insertion loss variations.

Attenuators Replacement Considerations

Consult Mini-Circuits documentation for direct substitutes within the DAT series. Verify electrical parameters such as attenuation range, frequency response, and package type before considering alternative models.
