Description
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.
The SKY65249-11 is packaged in a lead (Pb)-free, RoHS-compliant
laminate package, which measures 16 mm².
NEW Skyworks offers lead (Pb)-free, RoHS (Restriction of
Hazardous Substances)-compliant packaging.
