ZX76-31A-PPS+

Overview

The ZX76-31A-PPS+ is a digital step attenuator module from Mini-Circuits, operating from DC to 4000 MHz with a 50-ohm impedance. It provides a total attenuation range of 0 dB to 31 dB in 1 dB steps. The device features SMA connectors and supports a maximum input power of 24 dBm (0.25 Watt). Designed for robust performance, it operates within a temperature range of -40°C to +85°C. This module integrates control circuitry for precise signal level adjustment in RF systems.

Feature Summary

• Digital step control with 1 dB resolution across a 31 dB range
• Wideband operation from DC to 4 GHz
• Integrated SMA connectors for direct system integration
• High power handling capability up to 24 dBm

Applications

• Wireless communication base stations
• Test and measurement equipment
• RF signal conditioning circuits
• Military and aerospace radar systems

Procurement Notes

Verify the specific suffix 'PPS+' against the official Mini-Circuits datasheet to confirm connector type and package configuration. Ensure that the required attenuation steps and frequency range align with the DC-4000 MHz specification. Check for RoHS compliance status if environmental regulations apply to your assembly process. Confirm availability through authorized distributors as lead times may vary based on production schedules.

Selection Notes

Select this component when precise digital attenuation control is required over a wide bandwidth. The 1 dB step size offers fine granularity for signal leveling applications. Consider the 24 dBm power rating for high-power RF paths. The SMA interface simplifies prototyping and testing compared to surface-mount-only variants. Evaluate thermal management requirements given the operational temperature range.

Part Context

This part belongs to the ZX76 series of digital step attenuators by Mini-Circuits. The series is designed for RF and microwave applications requiring programmable attenuation. The 'PPS+' suffix typically denotes specific packaging and connector options within the product line. It serves as a critical component for dynamic range control in modern RF front-ends.

Replacement Considerations

Direct substitutes include other ZX76 series models with compatible attenuation ranges and interfaces. Verify pinout compatibility and control logic levels before swapping. Alternative brands may offer similar specifications but require validation of electrical parameters and mechanical dimensions.
