MAAT-010521-L2TR05

Overview

The MAAT-010521-L2TR05 is a voltage variable attenuator manufactured by MACOM Technology Solutions. It operates within a frequency range of 5.8 GHz to 12 GHz and features a nominal attenuation value of 0 dB. The component is designed for a system impedance of 50 Ohms. It is housed in a 16-VFQFN package with an exposed pad, suitable for surface-mount applications. This device provides analog control for attenuation adjustment.

Feature Summary

• Voltage variable attenuator with analog control capability
• Operates in the 5.8 GHz to 12 GHz frequency range
• Designed for 50 Ohm system impedance applications

Applications

• RF signal path attenuation
• Wireless communication systems
• Test and measurement equipment

Procurement Notes

Verify the specific ordering suffix L2TR05 against the manufacturer's current datasheet to ensure compatibility with required packaging and tape-and-reel specifications. Confirm that the 0 dB attenuation variant meets the design requirements, as other variants in the MAAT-010521 family offer different attenuation levels. Ensure the 16-VFQFN package footprint matches the PCB layout guidelines provided in the official documentation.

Selection Notes

Select this component when a fixed or minimal attenuation profile is required within the 5.8–12 GHz band. The 0 dB specification indicates it may serve primarily as a buffer or isolation element rather than a significant loss component. Compare against the broader MAAT-010521 series if higher attenuation values are needed, noting that the L2 suffix specifically denotes the 0 dB configuration.

Part Context

This part belongs to the MAAT-010521 family of voltage variable attenuators from MACOM. While the base model supports >30 dB attenuation, the L2 variant is configured for 0 dB operation. These devices are engineered for high linearity and are commonly integrated into RF front-end modules where precise signal level management is critical across microwave frequencies.

Replacement Considerations

The MAAT-010521-L1TR05 is a related part number within the same family but offers 37 dB of attenuation instead of 0 dB. Substitution requires careful evaluation of the circuit's attenuation requirements, as the electrical performance differs significantly between the two variants despite sharing similar packaging and frequency ranges.
