MAAV-011018-TR1000

Overview

The MAAV-011018-TR1000 is a voltage variable attenuator manufactured by MACOM Technology Solutions. It provides an attenuation range of 31 dB to 32 dB with analog control over a frequency band of 5 MHz to 3 GHz. The component operates at a system impedance of either 50 Ohms or 75 Ohms, depending on the specific configuration variant. It is housed in a compact 16-VFQFN package with an exposed pad, designed for surface-mount assembly in RF applications requiring precise signal level adjustment.

Feature Summary

• Provides analog voltage-controlled attenuation across a wide RF frequency spectrum
• Utilizes a compact lead-free 16-VFQFN package with exposed pad for thermal and mechanical stability
• Supports dual impedance configurations to accommodate varying system requirements

Applications

• CATV return path signal conditioning
• DOCSIS 3.1 system integration
• Wireless infrastructure bias networks

Procurement Notes

Verify the specific impedance requirement (50 Ohms vs. 75 Ohms) against the target circuit design before ordering, as datasheet listings indicate variations. Confirm the exact attenuation value specification (31 dB vs. 32 dB) aligns with the application's dynamic range needs. Ensure the 16-VFQFN footprint matches the PCB layout guidelines provided in the official MACOM datasheet to guarantee proper soldering and thermal performance.

Selection Notes

Select this component when a wideband, analog-controlled attenuator is required for frequencies up to 3 GHz. The choice between 50 Ohm and 75 Ohm variants depends strictly on the system impedance. Consider the 16-VFQFN package size constraints and the need for an exposed pad for heat dissipation. This device is suitable for applications demanding low distortion and stable performance in RF signal paths.

Part Context

The MAAV-011018 belongs to MACOM’s voltage variable attenuator family, designed for high-performance RF systems. It complements other MACOM components like the MAAV-011017, which offers similar functionality but extends the frequency range up to 12 GHz in a 3 mm PQFN package. These devices are integral to modern communication systems requiring precise gain management.

Replacement Considerations

The MAAV-011017 is a documented substitute offering extended frequency coverage up to 12 GHz in a comparable package. Verify that the higher frequency capability does not conflict with cost or size constraints. Ensure the replacement maintains the required analog control interface and impedance matching for the specific application.
