2.4GHz/5GHz LNA+SW Front-End-Module
RFIC 2019. 05 Update Rev2.2
DESCRIPTION
KEY FEATURES
Frequency range: 2.4GHz ~ 2.5GHz
• High IIP3: +1dBm
• High gain: 20dB
Frequency range: 5GHz ~ 5.9GHz
• High IIP3: +5dBm
• High gain: 14dB
• LNA Current Consumption: 14mA
• Small QFN (16-pin, 2.5 x 2.5 mm) package
The LS5601 is an high integration Front-End-
Module (FEM), included a SPDT
T/R switch
and a
low noise amplifier
(LNA) for wireless applications.
The device is typically operated at 3.3V and has
excellent NF of 2.2dB in the receiving mode . The
FEM is manufactured in a compact, 2.5 x 2.5
(mm),
16-pin, QFN leadless package.
The small footprint
provides designers the convenience when make
the compact product design, and still can meet the
system requirement easily .
Major Applications
• 802.11 a/b/g/n WLAN
• 802.11 ac WLAN
• 5 GHz ISM radio
• Notebook, Tablet etc portable device
• Router, Access point, Gateway
• Wireless video system
