描述 Description

The SKY65405-21 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 SKY65405-21

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 SKY65405-21, requiring only

four external components, enables the industry’s smallest PCB

area needed to implement a 2.4 GHz LNA.

A block diagram of the SKY65405-21 is shown in Figure 1. The

device package and pinout for the 6-pin Dual Flat No-Lead (DFN)

are shown in Figure 2. Signal pin assignments and functional pin

descriptions are described in Table 1.
