MAAD-007078-000100

Overview

The MAAD-007078-000100 is a GaAs FET 5-bit digital attenuator manufactured by MACOM Technology Solutions. It features an integral TTL driver and provides a total attenuation range of 1 dB to 31 dB with a step size of 1.0 dB. The device operates within a frequency range of 0 Hz to 3 GHz and maintains a 50 Ohm impedance. It is housed in a 32-PowerVFQFN surface-mount package and requires a 5 V operating supply voltage.

Feature Summary

• Integrates a TTL driver for direct logic control
• Utilizes GaAs FET technology for RF signal processing
• Provides precise 1.0 dB step resolution across the attenuation range

Applications

• Wireless communication systems
• RF integrated circuit testing
• Signal conditioning in RF front ends

Procurement Notes

Verify the specific suffix -000100 confirms the factory pack quantity of 100 units. Ensure compatibility with the 32-PowerVFQFN footprint during PCB layout. Confirm that the 5 V supply requirement aligns with the system power design. Check datasheet specifications for thermal management requirements associated with the SMD/SMT mounting style.

Selection Notes

Select this component when a 5-bit digital attenuation profile is required up to 31 dB. The integral TTL driver simplifies interface design compared to devices requiring external drivers. Verify that the 0 Hz to 3 GHz bandwidth meets the application's frequency needs. Consider the GaAs technology characteristics for noise and linearity performance relative to alternative semiconductor materials.

Part Context

This part belongs to the MAAD-0070xx series of digital attenuators from MACOM. These components are designed for wireless and RF applications requiring programmable signal loss. The series utilizes GaAs FET technology to achieve high performance in a compact surface-mount package. Other variants in the family may offer different attenuation ranges or frequency capabilities.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Evaluate alternatives based on matching 5-bit architecture, 32-PowerVFNN package, and 50 Ohm impedance. Verify that any replacement supports the same 1.0 dB step size and TTL control interface.
