SKY65404-31中文资料Low Noise Amplifiers数据手册Skyworks规格书

描述 Description

The SKY65404-31 is an ultra Low-Noise Amplifier (LNA) intendedfor 5 GHz wireless receiver applications. Its industry-leading NoiseFigure (NF), together with high linearity, makes it ideal as a firststageLNA in 802.11a Wireless Local Area Network (WLAN)radios.Operating with a single supply voltage, the SKY65404-31consumes only 10 mA of current. The device includes a shutdownmode to save power when the receiver is inactive.The tiny package footprint of the SKY65404-31, requiring onlyfour external components, enables the industry’s smallest PCBarea needed to implement a 5 GHz LNA.
