SKY65249-11: WLAN 802.11b, g, n
Intera™ Front-End Module
Features
Description
2.4 to 2.5 GHz operation
● Cardbus, mini PC1, PCIe and AP applications
● P
OUT @ 2.5% EVM (OFDM54): 18 dBm
● Gain: 25 dB
● Integrated PA, filters, directional detector and diversity switch
● Single supply voltage : 3.0 to 3.6 V
● Dual antennas
● Small, ultra thin package 4 x 4 x 0.9 mm
● Lead (Pb)-free and RoHS-compliant
The SKY65249-11 Intera FEM contains one complete 2.4 GHz
transmit/receive chain in a compact RF front-end module
optimized for single band 2.4–2.5 GHz operation. The
SKY65249-11 includes a PA with integrated input filtering for
3.2–3.3 GHz rejection, and temperature-compensated directional
power detector with 20 dB dynamic range. Also included are low
loss, high rejection harmonic filters and a diversity switch which
provide high linearity in transmit and low loss in receive paths.
●
NEW
The SKY65249-11 is packaged in a lead (Pb)-free, RoHS-compliant
laminate package, which measures 16 mm2.
Skyworks offers lead (Pb)-free, RoHS (Restriction of
Hazardous Substances)-compliant packaging.

CAUTION: Although this device is designed to be as robust as possible, Electrostatic Discharge (ESD) can damage this device. This
device must be protected at all times from ESD. Static charges may easily produce potentials of several kilovolts on the
human body or equipment, which can discharge without detection. Industry-standard ESD precautions should be employed
at all times.
