MAAD-008790-0001TR

Overview

The MAAD-008790-0001TR is a GaAs pHEMT 5-bit digital attenuator manufactured by MACOM Technology Solutions. It features an integral TTL driver and operates within a frequency range of 0 Hz to 4 GHz. The device provides a total attenuation value ranging from 1 dB to 31 dB. Designed to minimize phase variation over the operating band, it utilizes a parallel and serial control interface with power-up state selection capabilities. The component is RoHS compliant and classified under ECCN EAR99.

Feature Summary

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

Applications

• RF signal path attenuation in wireless communication systems
• Phase array antenna beam steering networks
• Test and measurement equipment requiring precise digital gain control

Procurement Notes

Verify the specific ordering suffix to ensure compatibility with required packaging and tape-and-reel specifications. Confirm that the supplier provides original manufacturer documentation to guarantee authenticity. Check for RoHS compliance status if environmental regulations apply to your assembly process. Ensure the lead time aligns with production schedules, as standard delivery periods may vary based on current market availability and manufacturing constraints.

Selection Notes

Select this component when a 5-bit resolution with up to 31 dB of attenuation is required within a DC to 4 GHz bandwidth. The integrated TTL driver simplifies system design by eliminating external control circuitry. Consider the minimized phase variation characteristic for applications demanding stable signal phase integrity during attenuation adjustments. Verify impedance matching requirements against the system architecture before integration.

Part Context

This part belongs to MACOM's family of GaAs pHEMT digital attenuators. It shares architectural similarities with other models like the MAAD-008791, though bit resolution and frequency ranges differ. The series is designed for robust performance in RF environments, offering reliable attenuation control through digital interfaces. Understanding the broader product line helps in identifying suitable alternatives or upgrades for evolving system requirements.

Replacement Considerations

The MAAD-008791-0001TR is a documented alternative offering 6-bit resolution and a 3.0 GHz frequency range. Verify pinout compatibility and control logic differences before substitution. Ensure the replacement meets the specific attenuation and phase variation requirements of the application.
