AA116-72LF

Attenuators Overview

The AA116-72LF is a 1-bit GaAs FET digital attenuator manufactured by Skyworks Solutions Inc. It operates within a frequency range of 4 MHz to 2 GHz and features a single attenuation step of 15 dB. The device maintains a characteristic impedance of 50 ohms with an insertion loss of 0.5 dB. Designed for surface-mount applications, it utilizes the SOT-5 package. The component supports a supply voltage of 3 V and functions reliably across a temperature range of -40 °C to +85 °C.

Attenuators Feature Summary

• Utilizes GaAs FET technology for digital signal attenuation
• Provides a fixed 15 dB attenuation step in a 1-bit configuration
• Operates effectively from 4 MHz up to 2 GHz
• Designed for low-cost surface-mount integration

Attenuators Applications

• RF signal conditioning in wireless infrastructure
• Attenuation control in mobile communication systems
• Test and measurement equipment requiring precise signal level adjustment

Attenuators Procurement Notes

Verify current availability status as the manufacturer has indicated this component is scheduled for obsolescence. Confirm that the specific SOT-5 package variant matches your PCB footprint requirements. Ensure that the 1-bit 15 dB attenuation specification aligns with your system's dynamic range needs before finalizing procurement plans.

Attenuators Selection Notes

Select this component when a simple, high-isolation 15 dB attenuation step is required within the 4 MHz to 2 GHz band. Consider the SOT-5 package size for space-constrained designs. Verify that the 3 V control voltage interface is compatible with your system's logic levels. Evaluate the need for additional bits if variable attenuation beyond a single step is necessary.

Attenuators Part Context

The AA116-72LF belongs to Skyworks' family of digital attenuators designed for RF applications. It complements other models like the AA103-72LF, which offers different attenuation values. This specific part focuses on providing a robust, single-step attenuation solution using GaAs technology, distinct from multi-bit or variable attenuator options available in the broader product line.

Attenuators Replacement Considerations

Public confirmed substitute part numbers are not provided in the source documentation. Due to the scheduled obsolescence status, alternative components must be identified through independent cross-reference analysis based on matching electrical parameters such as 15 dB attenuation, 1-bit resolution, and 50 ohm impedance.
