SKY85735-21

RF Front End (LNA + PA) Overview

The SKY85735-21 is a front-end module (FEM) designed for 5.8 GHz WLAN applications, supporting 256QAM modulation schemes. It integrates a power amplifier (PA), switch (SW), and low-noise amplifier (LNA) within a compact package. The device operates at an operating supply voltage of 5 V and utilizes an MCM-12 surface-mount package. This integrated solution facilitates efficient signal transmission and reception in wireless local area network systems.

RF Front End (LNA + PA) Procurement Notes

Verify the specific ordering suffix to ensure correct packaging configuration, such as tape and reel or cut tape options. Confirm that the component meets the required moisture sensitivity level (MSL 3) and handling precautions during assembly. Cross-reference the manufacturer part number with official Skyworks documentation to validate authenticity and technical specifications before procurement.

RF Front End (LNA + PA) Selection Notes

Select this component for designs requiring a compact, integrated RF solution for 5.8 GHz WLAN operations. The MCM-12 package offers space efficiency for dense PCB layouts. Ensure the system design supports the 5 V operating supply voltage. Consider the integration of PA, SW, and LNA to simplify board architecture and reduce component count compared to discrete solutions.

RF Front End (LNA + PA) Part Context

This part belongs to Skyworks Solutions' family of RF front-end modules tailored for wireless connectivity. It complements other variants like the SKY85735-11, which targets 5 GHz bands.
