MAATCC0014

Overview

The MAATCC0014 is a GaAs FET digital attenuator manufactured by MACOM Technology Solutions. It features an integral TTL driver and provides a total attenuation range of 15.5 dB with a step size of 0.5 dB. The device operates within a frequency range of 0 Hz to 3.5 GHz and maintains a 50 Ohm impedance. It is housed in a 32-PowerVFQFN package. Key electrical specifications include a maximum VSWR of 2 and an insertion loss of 4.2 dB. The component supports operation temperatures from -40°C to +85°C and is classified as a 5-bit variable attenuator.

Feature Summary

• Integrates a TTL driver for direct logic control compatibility
• Utilizes GaAs FET technology for high-frequency performance
• Provides precise 0.5 dB step resolution across the attenuation range

Applications

• RF signal path attenuation in communication systems
• Test and measurement equipment requiring variable gain control
• Wireless infrastructure components

Procurement Notes

Verify the specific package variant, as sources indicate both 32-PowerVFQFN and other configurations. Confirm the frequency rating matches your application requirements, noting discrepancies between DC-2 GHz and DC-3.5 GHz data points in public listings. Ensure the TTL driver interface aligns with your system logic levels before procurement.

Selection Notes

Select this component when a compact, digitally controlled attenuator with integrated driving circuitry is required. The GaAs FET construction supports wideband operation up to 3.5 GHz. Consider the 32-pin PowerVFQFN footprint for PCB layout constraints. Verify thermal management capabilities given the operating temperature range and power dissipation characteristics inherent to the package type.

Part Context

This part belongs to MACOM's MAATCC series of digital attenuators. These devices are designed for applications requiring reliable RF signal control with minimal external components due to the integrated driver. The series typically offers various bit resolutions and attenuation ranges to suit different system architectures.
