MAAVSS0008TR

Overview

The MAAVSS0008TR is a GaAs MMIC voltage variable absorptive attenuator manufactured by MACOM Technology Solutions. It operates within a frequency range of 500 MHz to 2 GHz and features a nominal attenuation value of 30 dB. The device maintains a system impedance of 50 Ohms and is housed in an 8-SOIC surface mount package with a width of 3.90 mm. It supports a maximum VSWR of 2 and functions reliably across an operating temperature range from -40°C to +85°C.

Feature Summary

• Utilizes GaAs MMIC technology for high-performance RF signal control
• Provides linear voltage-variable absorption characteristics
• Designed for lead-free surface mount integration

Applications

• RF signal path attenuation in wireless communication systems
• Gain control stages in receiver front-ends
• Test and measurement equipment requiring precise signal level adjustment

Procurement Notes

Verify the specific suffix (e.g., TR vs TR-3000) against the manufacturer's official datasheet to confirm packaging quantity and substrate technology, as variations exist between GaAs and Si implementations. Ensure the required attenuation tolerance and insertion loss specifications align with the design requirements before finalizing procurement orders.

Selection Notes

Select this component when a wide dynamic range of attenuation is required within the 500 MHz to 2 GHz band. The SOIC-8 package facilitates automated surface mounting. Consider the thermal management capabilities if operating near the upper temperature limit, and verify that the control voltage interface matches the system's drive circuitry.

Part Context

This part belongs to the MAAVSS series of voltage variable attenuators from MACOM. It serves as a critical passive-active hybrid component for managing signal power levels in RF circuits. The series is known for its compact form factor and consistent performance across varying environmental conditions.

Replacement Considerations

Check for direct substitutes such as the MAAVSS0006TR for different attenuation ranges or frequency bands. Verify pin compatibility and electrical parameters before swapping components to ensure circuit integrity.
