SKY85753-11

RF Front End (LNA + PA) Overview

The SKY85753-11 is a 5 GHz RF Front End Module (FEM) designed for 802.11n/ac WLAN applications. It integrates a power amplifier, low noise amplifier, SPDT switch, and power detector within a QFN-16 package measuring 2.3x2.3 mm. The device operates at 5V with a typical output power of 20.5 dBm and provides 12 dB gain across the 5.15 GHz to 5.85 GHz frequency range.

RF Front End (LNA + PA) Feature Summary

• Integrates PA, LNA, SPDT switch, and power detector in a compact footprint
• Optimized for high linearity and efficiency in 5 GHz WLAN systems
• Supports standard 802.11n/ac protocols with integrated control logic

RF Front End (LNA + PA) Applications

• Compact Wi-Fi routers and access points

RF Front End (LNA + PA) Procurement Notes

Verify component authenticity through authorized Skyworks distributors or direct manufacturer channels. Confirm lot traceability and RoHS compliance status prior to integration. Ensure handling procedures meet ESD sensitivity requirements for the exposed pad QFN package to prevent thermal or electrical damage during assembly.

RF Front End (LNA + PA) Selection Notes

Select this module for designs requiring high output power and integrated switching in limited PCB space. Evaluate thermal management capabilities due to the dense integration. Compare against newer generations if long-term supply stability is critical, as lifecycle status should be confirmed before finalizing the bill of materials.
