DAT-31R5A-PN+

Attenuators Overview

The DAT-31R5A-PN+ is a surface-mount digital step attenuator from Mini-Circuits, operating from DC to 4000 MHz with a 50 Ohm impedance. It provides an attenuation range of 0 to 31.5 dB in 0.5 dB steps using a 6-bit control interface. The device features a maximum VSWR of 1.9:1 and an insertion loss of 2.1 dB. It operates within a temperature range of -40°C to +85°C and is housed in a compact package suitable for automated assembly.

Attenuators Feature Summary

• Provides precise digital attenuation adjustment in fine 0.5 dB increments across a wide dynamic range
• Utilizes a 6-bit parallel control interface for direct logic-level integration
• Designed for high-reliability surface-mount applications with robust RF performance

Attenuators Applications

• RF signal path calibration and level setting
• Test and measurement equipment requiring programmable attenuation
• Wireless communication systems for gain control

Attenuators Procurement Notes

Verify the specific suffix PN+ confirms the parallel interface variant, as other suffixes may indicate serial control or different packaging. Ensure the order quantity matches standard reel sizes if applicable. Confirm that the 50 Ohm system impedance aligns with your circuit design requirements before finalizing procurement.

Attenuators Selection Notes

Select this component when fine resolution attenuation is required up to 4 GHz. The 6-bit parallel interface suits designs where pin count allows for multiple control lines. Consider the 0.5 dB step size against simpler 1 dB or 3 dB step alternatives if lower cost or fewer control pins are prioritized over precision.

Attenuators Part Context

This part belongs to the DAT series of digital step attenuators by Mini-Circuits. The series offers various attenuation ranges and step sizes. The DAT-31R5A-PN+ specifically targets applications needing high-resolution control within a moderate frequency band, distinguishing it from higher-frequency or coarser-step variants in the product line.

Attenuators Replacement Considerations

Check for DAT-31R5A-SP+ if a serial interface is preferred instead of parallel. Verify compatibility with DAT-31A-SP+ if 1 dB steps are acceptable. Ensure any substitute maintains the 50 Ohm impedance and similar thermal characteristics.
