SKY65404-31

5 GHz Low Noise Amplifier

The SKY65404-31 is an ultra Low-Noise Amplifier (LNA) intended for 5 GHz wireless receiver applications. Its industry-leading Noise Figure (NF), together with high linearity, makes it ideal as a firststage LNA in 802.11a Wireless Local Area Network (WLAN) radios.

Operating with a single supply voltage, the SKY65404-31 consumes only 10 mA of current. The device includes a shutdown mode to save power when the receiver is inactive. The tiny package footprint of the SKY65404-31, requiring only four external components, enables the industry’s smallest PCB area needed to implement a 5 GHz LNA.
