MAAVSS0004

Overview

The MAAVSS0004 is a GaAs MMIC voltage variable absorptive attenuator manufactured by MACOM Technology Solutions. It operates within a frequency range of 0 Hz to 2 GHz and provides a nominal attenuation of 35 dB. The device features a 50 Ohm impedance and utilizes a 14-lead SOIC surface mount plastic package with a width of 0.154 inches (3.90 mm). It supports linear control characteristics and low voltage power supply operation, designed for reliable performance across an operating temperature range of -40°C to +85°C.

Feature Summary

• Integrates GaAs MMIC technology for compact surface mount implementation in a 14-lead SOIC package.
• Provides voltage-controlled variable attenuation with linear response characteristics over the DC to 2 GHz bandwidth.
• Designed for low voltage power supply operation to facilitate integration into portable and battery-powered systems.

Applications

• RF signal conditioning in telecommunications infrastructure
• Gain control stages in wireless communication systems
• Test and measurement equipment requiring precise attenuation

Procurement Notes

Verify the specific datasheet revision and ordering suffixes directly with MACOM or authorized distributors before procurement. Confirm that the 14-lead SOIC footprint matches your PCB layout requirements. Ensure that the thermal management capabilities of the target application align with the component's specified operating temperature range of -40°C to +85°C. Cross-reference the electrical specifications against your system's impedance and frequency requirements to guarantee compatibility.

Selection Notes

Select the MAAVSS0004 when a wide dynamic range of attenuation up to 35 dB is required within the 2 GHz spectrum. This component is suitable for designs prioritizing a balance between high isolation and low insertion loss in a small form factor. Consider its GaAs construction for robust RF performance compared to silicon alternatives. Evaluate the linear control characteristic if precise analog attenuation steps are necessary for the application.

Part Context

The MAAVSS0004 belongs to MACOM's family of voltage variable absorptive attenuators, which utilize monolithic microwave integrated circuit (MMIC) technology. These components are engineered to provide continuous attenuation control via a single DC voltage input. The series is characterized by its use of gallium arsenide substrates to achieve high-frequency performance while maintaining a compact surface-mount profile suitable for modern electronic assemblies.
