ZX76-31R5A-PPS+

Overview

The ZX76-31R5A-PPS+ is a 6-bit digital step attenuator from Mini-Circuits, designed for RF applications. It provides a total attenuation range of 31.5 dB with a resolution of 0.5 dB per step. The device operates over a frequency range of DC to 4000 MHz and maintains a 50-ohm impedance. It features parallel control inputs and requires a single positive supply voltage. The component is housed in an SMT package and supports RoHS and REACH compliance standards.

Feature Summary

• Six-bit digital control architecture enabling precise attenuation steps
• Wideband operational capability spanning from DC to 4 GHz
• Single positive supply voltage requirement simplifying power integration
• Parallel interface design for straightforward logic control

Applications

• RF signal path gain management in communication systems
• Test and measurement equipment requiring variable attenuation
• Phased array antenna beamforming networks
• Wireless infrastructure signal conditioning

Procurement Notes

Verify the specific suffix PPS+ against the official Mini-Circuits datasheet to confirm packaging type and tape/reel specifications. Ensure that the parallel control interface requirements match your system's logic levels. Confirm RoHS compliance status if environmental regulations apply to your deployment. Cross-reference the SMA connector variant details if applicable to your assembly needs.

Selection Notes

Select this component when a wide bandwidth up to 4 GHz is required alongside fine 0.5 dB resolution. The parallel control interface is suitable for systems where serial protocols are not preferred or available. Consider the single supply voltage constraint during power budget analysis. Verify that the 50-ohm impedance matches the surrounding circuit topology to minimize reflections.

Part Context

This model belongs to the ZX76 series of digital step attenuators by Mini-Circuits. The series offers various attenuation ranges and control interfaces. The ZX76-31R5A-PPS+ specifically denotes the 31.5 dB range variant with parallel control. It is part of Mini-Circuits' portfolio of RF and microwave components designed for high-performance signal processing.

Replacement Considerations

Check Mini-Circuits documentation for direct pin-compatible alternatives within the ZX76 family. Verify if other models offer different attenuation ranges or control interfaces such as serial options. Ensure any substitute maintains the DC to 4000 MHz frequency range and 50-ohm impedance characteristics.
