MAAD-007083-0001TR

Overview

The MAAD-007083-0001TR is a GaAs FET-based digital attenuator from MACOM Technology Solutions, designed for broadband RF applications. It features a continuous frequency range from DC to 6 GHz and operates with a standard 50 Ohm impedance. The device provides a total attenuation range of 31 dB using a 5-bit architecture with a precise 1 dB step size. Packaged in a compact PQFN-32 surface-mount format, it includes an integral TTL driver for simplified control. The component supports a maximum power rating of 34 dBm and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Integrates a TTL driver directly on the die for straightforward logic-level control
• Utilizes GaAs FET technology to ensure high linearity and low insertion loss across the bandwidth
• Offers fine 1 dB resolution steps for precise signal level adjustment

Applications

• Satellite communication systems requiring variable gain control
• Wireless infrastructure base stations
• Test and measurement instrumentation equipment

Procurement Notes

Verify that the specific suffix TR indicates tape and reel packaging rather than tray packaging when placing orders. Confirm the exact part number matches the required 32-pin PQFN footprint. Ensure compatibility with the specified 5V operating voltage and TTL logic levels before integration into the design.

Selection Notes

Select this component when a wideband digital solution is required up to 6 GHz. The integrated driver simplifies PCB layout by reducing external control circuitry. Consider the 34 dBm power handling capability for high-power RF paths. The 5-bit resolution may be insufficient for applications requiring finer attenuation granularity beyond 1 dB steps.

Part Context

This model belongs to the MAAD series of monolithic microwave integrated circuits. It represents a specialized class of digitally controlled attenuators optimized for space-constrained designs. The use of Gallium Arsenide (GaAs) technology distinguishes it from silicon-based alternatives, offering superior performance at microwave frequencies.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify pinout compatibility and electrical specifications carefully if considering alternative manufacturers' devices.
