PRODUCT SUMMARY SKY65405-11: 2.4 GHz Low-Noise Amplifier Applications Description x 802.11b,g WLANs The SKY65405-11 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. x 2.4 GHz ISM radios x SmartPhones x Notebooks, netbooks, tablets 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. x Routers, access points, gateways Features 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. x Ultra-low Noise Figure: 1.0 dB x 2.4 GHz to 2.5 GHz operation 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. x Enable/disable mode x High IIP3: +9 dBm x High gain: 14 dB x 2.8 to 5.0 V single-supply operation x QFN (6-pin, 1.5 x 1.5 mm) package (MSL3, 260 qC per JEDEC J-STD-020) Skyworks offers lead (Pb)-free RoHS (Restriction of Hazardous Substances) compliant packaging.
