SKY85610-11

RF Front End (LNA + PA) Overview

The SKY85610-11 is an integrated RF front-end module designed for 5 GHz 802.11ac WLAN applications. It combines a single-pole double-throw (SPDT) switch with a low-noise amplifier (LNA). The device operates within a frequency range of 4.9 to 5.9 GHz and features a noise figure of 2.5 dB. It supports supply voltages from 3 V to 5.5 V with a typical operating current of 12 mA. The component is housed in a QFN-16 package measuring 2.5x2.5 mm, suitable for surface-mount installation across temperatures from -40 C to +85 C.
