MAAD-008790-000100

Overview

The MAAD-008790-000100 is a GaAs pHEMT 5-bit digital attenuator from MACOM Technology Solutions. It operates within a frequency range of 0 Hz to 4 GHz and provides an attenuation range of 1 dB to 31 dB in discrete steps. The device features a 50 Ohm impedance and includes an integral TTL driver for control. It is housed in a 32-PowerVFQFN package, designed to minimize phase variation across its operating band.

Feature Summary

• Utilizes GaAs pHEMT technology for high-performance signal attenuation
• Integrates a TTL driver for simplified digital control interface
• Engineered to minimize phase variation over the operational frequency range

Applications

• Wireless communication systems requiring precise signal level adjustment
• RF test and measurement equipment
• Phased array antenna beamforming networks

Procurement Notes

Verify the specific datasheet revision (e.g., Rev. V2) against your design requirements before procurement. Ensure that the 32-PowerVFQFN package footprint matches your PCB layout constraints. Confirm that the integral TTL driver voltage levels are compatible with your system's logic supply. Cross-reference the manufacturer part number with authorized distributors to ensure authenticity and traceability.

Selection Notes

Select this component when a constant-phase digital attenuator is required for frequencies up to 4 GHz. The 5-bit resolution offers 31 dB of attenuation, suitable for applications needing fine-grained control. Consider the PowerVFQFN package for compact designs. Verify that the GaAs pHEMT technology meets your linearity and power handling needs compared to alternative semiconductor technologies.

Part Context

This part belongs to MACOM's family of digital attenuators designed for RF and microwave applications. Unlike variable analog attenuators, this model uses digital bits to set attenuation levels. It is distinct from other MACOM models by its specific 5-bit configuration and integrated driver, targeting applications where phase stability is critical across the DC to 4 GHz spectrum.

Replacement Considerations
