SKY12408-321LF

Attenuators Overview

The SKY12408-321LF is a GaAs digital attenuator from Skyworks Solutions, designed for differential signal paths. It operates within a frequency range of 50 MHz to 600 MHz and features a nominal impedance of 100 Ohms. The device provides 6 dB of attenuation with a 2-bit control interface. Key electrical specifications include an insertion loss of 0.3 dB and a maximum operating temperature of +85°C. The component is housed in a 12-WFQFN exposed pad package.

Attenuators Feature Summary

• Utilizes Gallium Arsenide (GaAs) technology for high-performance RF attenuation
• Supports differential signal processing with 100 Ohm impedance matching
• Features a compact 12-WFQFN package suitable for space-constrained designs

Attenuators Applications

• Wireless infrastructure equipment requiring precise signal level control
• Test and measurement instruments needing stable RF attenuation
• Broadband communication systems operating between 50 MHz and 600 MHz

Attenuators Procurement Notes

Verify the current lifecycle status before integration, as this component is listed as End-of-Life (EOL). Confirm that the specific 12-WFQFN package and GaAs construction meet your design requirements. Ensure compatibility with the 2-bit control logic and 100 Ohm differential impedance. Check for available replacement alternatives if long-term supply continuity is required.

Attenuators Selection Notes

Select this part when a differential 6 dB attenuator is needed for frequencies up to 600 MHz. The low insertion loss of 0.3 dB makes it suitable for applications where signal integrity is critical. Consider the 100 Ohm impedance requirement for proper matching. The GaAs technology offers robust performance in wireless environments. Evaluate the EOL status against production volume needs.

Attenuators Part Context

This component belongs to Skyworks' portfolio of GaAs digital attenuators. It is specifically engineered for differential applications, distinguishing it from single-ended variants in the same family. The 12-WFQFN package allows for surface-mount assembly. It serves as a passive control element in RF signal chains, providing fixed attenuation levels via digital inputs.

Attenuators Replacement Considerations

SKY12407-321LF: Offers similar 2-bit control but differs in channel count and attenuation value.
