Description
The SKY65404-31 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 first-
stage LNA in 802.11a Wireless Local Area Network (WLAN)
radios.
Operating with a single supply voltage, the SKY65404-31
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 SKY65404-31, requiring only
four external components, enables the industry’s smallest PCB
area needed to implement a 5 GHz LNA.
A block diagram of the SKY65404-31 is shown in Figure 1. The
device package and pinout for the 6-pin Quad Flat No-Lead (QFN)
are shown in Figure 2.

DATA SHEET • SKY65404-31: 5 GHZ LNA
Technical Description
The SKY65404-31 is matched at the RF output port (pin 4) and
requires only a shunt capacitor match at the RF input port (pin 3).
The VCC signal (pin 6) requires a simple bypass circuit. An
external resistor on the V_ENABLE signal (pin 1) allows a wide
range of control voltages to be used. Shutdown mode is achieved
by switching the V_ENABLE signal to 0 V.
Package and Handling Information
Since the device package is sensitive to moisture absorption, it is
baked and vacuum packed before shipping. Instructions on the
shipping container label regarding exposure to moisture after the
container seal is broken must be followed. Otherwise, problems
related to moisture absorption may occur when the part is
subjected to high temperature during solder assembly.
The SKY65404-31 is rated to Moisture Sensitivity Level 1 (MSL1)
at 260 C. It can be used for lead or lead-free soldering. For
additional information, refer to the Skyworks Application Note,
Solder Reflow Information, document number 200164.
Care must be taken when attaching this product, whether it is
done manually or in a production solder reflow environment.
Production quantities of this product are shipped in a standard
tape and reel format.
