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.
