Introduction

The SKY65405-21 is an ultra-low-noise amplifier (LNA) intended for 2.4 GHz wireless receiver applications. Its industry-leading noise figure (NF), together with high linearity, makes it ideal as a first-stage LNA in 802.11b/g wireless local area network (WLAN) radios. Operating with a single supply voltage, the SKY65405-21 consumes only 12 mA of current. The device includes a shutdown mode to save power when the receiver is inactive. The tiny package footprint of the SKY65405-21, requiring only four external components, enables the industry’s smallest PCB area needed to implement a 2.4 GHz LNA.
