SKY65405-21中文资料2.4 GHz Low Noise Amplifier数据手册Skyworks规格书

描述 Description

The SKY65405-21 is an ultra Low-Noise Amplifier (LNA) intendedfor 2.4 GHz wireless receiver applications. Its industry-leadingNoise Figure (NF), together with high linearity, makes it ideal as afirst-stage LNA in 802.11b,g Wireless Local Area Network (WLAN)radios.

Operating with a single supply voltage, the SKY65405-21consumes only 12 mA of current. The device includes a shutdownmode to save power when the receiver is inactive.

The tiny package footprint of the SKY65405-21, requiring onlyfour external components, enables the industry’s smallest PCBarea needed to implement a 2.4 GHz LNA.
