SKY85302-11

RF Front End (LNA + PA) Overview

The SKY85302-11 is a modular front-end module (FEM) designed for 2.4 GHz Bluetooth and WLAN applications, supporting up to 256 QAM modulation schemes. It integrates a high-performance power amplifier (PA), harmonic filter, low noise amplifier (LNA) with bypass capability, and a transmit/receive (T/R) switch. The device features fully matched input and output impedances to simplify system integration. It operates at a supply voltage of 3.6 V and is housed in a compact 16-QFN package measuring 2.5x2.5 mm with an exposed pad.
