ZX76-15R5A-PPS+

Overview

The ZX76-15R5A-PPS+ is a 5-bit digital step attenuator manufactured by Mini-Circuits, designed for RF applications from DC to 4000 MHz. It features a parallel control interface and operates on a single positive supply voltage. The module provides an attenuation range of 0 dB to 15.5 dB with 50-ohm impedance. It utilizes SMA connectors for interconnection and is housed in a compact surface-mount package suitable for board integration.

Feature Summary

• Provides precise digital step attenuation control via a parallel interface
• Operates over a wide frequency range from DC to 4 GHz
• Designed for single positive supply voltage input
• Integrates SMA connectors for direct system interfacing

Applications

• RF signal path power management
• Wireless communication systems
• Test and measurement equipment
• Military and aerospace radar systems

Procurement Notes

Verify the specific suffix 'PPS+' against the official Mini-Circuits datasheet to confirm pinout and connector configuration. Ensure the order quantity meets the manufacturer's minimum requirements. Confirm RoHS compliance status if required for your assembly process. Check lead times as they may vary based on production schedules. Validate that the 50-ohm impedance matches your system design specifications before finalizing the purchase.

Selection Notes

Select this component when a compact, digitally controlled attenuator is needed for frequencies up to 4 GHz. The parallel control interface simplifies logic connections compared to serial alternatives. Consider the single-supply requirement for power budgeting. The integrated SMA connectors reduce PCB space usage but require appropriate cable or adapter interfaces. Evaluate thermal performance if operating at high attenuation levels continuously.

Part Context

This part belongs to the ZX76 series of digital step attenuators from Mini-Circuits. The series offers various attenuation steps and control interfaces. The '15R5A' designation indicates the 15.5 dB total attenuation capability. The 'PPS+' suffix typically denotes the specific package type and connector style. This model is part of Mini-Circuits' portfolio of RF and microwave components used in signal processing applications.

Replacement Considerations

Direct substitutes include other Mini-Circuits models like the ZX76-31R5A-PPS+ for higher attenuation needs. Cross-reference pinouts and control logic with competitors such as Analog Devices or Qorvo if sourcing from alternative vendors. Ensure frequency range and impedance match exactly. Verify that the replacement supports the same single-supply voltage operation.
