SKY65981-11

5 GHz, 802.11ac/n Low-Noise Amplifier


The SKY65981-11 is an ultra Low-Noise Amplifier (LNA) intended for 5 GHz, IEEE 802.11ac/n wireless receiver applications. Its industry-leading Noise Figure (NF), together with high linearity, make it ideal as a first-stage LNA in IEEE 802.11ac/n Wireless Local Area Network (WLAN) radios.

Operating with a single supply voltage, the SKY65981-11 consumes only 12 mA of current. The device includes a bypass mode for near field applications and to save power when the receiver is inactive.

The tiny package footprint of the SKY65981-11, requiring only four external components, enables the industry’s smallest PCB area needed to implement a fully-matched 5 GHz LNA.
