DAT-31R5A-SN+

Attenuators Overview

The DAT-31R5A-SN+ is a surface-mount digital step attenuator from Mini-Circuits, operating from DC to 4000 MHz with a 50 Ohm impedance. It provides a total attenuation range of 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 typical insertion loss of 2.1 dB. Packaged in a 20-VFQFN exposed pad (4 mm x 4 mm), it supports operation between -40°C and +85°C.

Attenuators Feature Summary

• Digital step control via 6-bit parallel interface for precise attenuation adjustment
• Compact surface-mount design suitable for automated assembly
• Wide frequency coverage from DC to 4 GHz

Attenuators Applications

• RF test and measurement equipment calibration
• Wireless communication base station signal conditioning
• Phased array antenna beamforming networks

Attenuators Procurement Notes

Verify the specific suffix 'SN+' against the manufacturer's current datasheet to confirm package type and pinout compatibility. Ensure the ordering code matches the required 20-VFQFN configuration. Cross-reference RoHS compliance status directly with the official documentation before procurement.

Attenuators Selection Notes

Select this component when precise 0.5 dB resolution is required within a 31.5 dB range up to 4 GHz. Compare against the DAT-31A-SP+ if a 1 dB step size is acceptable. Consider the 20-VFQFN footprint requirements for PCB layout and thermal management during integration.

Attenuators Part Context

This part belongs to the Mini-Circuits DAT series of digital step attenuators. These components are designed for high-performance RF applications requiring reliable signal level control. The series offers various attenuation ranges and step sizes to suit different system architectures.

Attenuators Replacement Considerations

The DAT-31R5A-PN+ is a confirmed substitute offering identical electrical specifications but utilizes a different package style.
