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 SKY65405-11
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 SKY65405-11
requiring only four external components, enables the industry?s smallest PCB area needed to implement a 2.4 GHz LNA. The device package and pinout for the 6-pin Quad Flat No-Lead (QFN) are shown in Figure 1 and a block diagram of the SKY65405 is shown in Figure 2.
