MAATSS0022TR-3000

Overview

The MAATSS0022TR-3000 is a GaAs MMIC digital attenuator from MACOM Technology Solutions, operating within a frequency range of 400 MHz to 2500 MHz. It provides a total attenuation range of 15.5 dB with 0.5 dB least significant bit (LSB) steps across five bits. The device features a maximum insertion loss of 2.5 dB and supports a maximum continuous wave input power of 33.98 dBm. Designed for 50 Ω systems, it utilizes a lead-free MSOP-10 package and operates on control voltages between +3V and +5V. It complies with RoHS3 standards.

Feature Summary

• Utilizes GaAs MMIC technology for high reliability in a compact surface-mount package
• Provides precise digital attenuation control with 0.5 dB resolution steps
• Operates with standard logic-level control voltages ranging from +3V to +5V

Applications

• RF signal path gain adjustment in communication systems

Procurement Notes

Verify the specific suffix -3000 against the manufacturer datasheet to confirm reel quantity and tape-and-reel specifications. Ensure the procurement documentation explicitly states RoHS3 compliance status. Cross-reference the MSOP-10 package dimensions with the official mechanical drawing to guarantee board layout compatibility. Confirm that the component marking aligns with the current production revision indicated in public engineering change notices.

Selection Notes

Select this component when a wideband digital attenuator is required for frequencies up to 2.5 GHz. The 15.5 dB range and 0.5 dB step size suit applications needing fine-grained signal control. Consider the 50 Ω impedance match for system integration. Evaluate the thermal performance at the maximum specified operating temperature of 85 °C. Ensure the control interface voltage levels are compatible with the +3V to +5V requirement.
