Description
High IIP3: +7 dBm
The SKY65404-21 is an ultra Low-Noise Amplifier (LNA) intended
for 5 GHz wireless receiver applications. Its industry-leading Noise
Figure (NF), together with high linearity, makes it ideal as a firststage LNA in 802.11a Wireless Local Area Network (WLAN)
radios.
High gain: 13 dB
2.8 to 5.0 V single-supply operation
QFN (6-pin, 1.5 x 1.5 mm) package (MSL1, 260 C per JEDEC
J-STD-020)
Skyworks offers lead (Pb)-free RoHS (Restriction of
Hazardous Substances) compliant packaging.
Operating with a single supply voltage, the SKY65404-21
consumes only 10 mA of current. The device includes a shutdown
mode to save power when the receiver is inactive.
The tiny package footprint of the SKY65404-21, requiring only
four external components, enables the industry’s smallest PCB
area needed to implement a 5 GHz LNA.
A block diagram of the SKY65404-21 is shown in Figure 1.
