SKY85703-11

RF Front End (LNA + PA) Overview

The SKY85703-11 is a highly integrated 5 GHz Front-End Module (FEM) designed for 802.11ac WLAN applications. It incorporates a single-pole double-throw (SPDT) transmit/receive switch, a power amplifier (PA), and a low-noise amplifier (LNA) with bypass functionality. The device features fully matched input and output interfaces to simplify RF design integration. Key electrical specifications include a gain of 30 dB and an output power (Pout) of 16 dBm. The component is housed in a compact 16-pin QFN package measuring 3x3 mm.
