Description
The SKY65227-11 Intera nFEM contains two complete 2.4 GHz
transmit/receive chains in one compact RF front-end module
optimized for single band 2.4 GHz MIMO (multiple in—multiple out)
operation, in compliance with the 802.11n draft standard. The
SKY65227-11 includes two 2 GHz PAs with integrated input fil-
tering for 3–4 GHz rejection, and temperature-compensated,
directional power detector with 20 dB dynamic range. Also included
are low loss, high rejection GaAs harmonic filters and T/R switches
which provide high linearity in all transmit paths and low loss in all
receive paths.
The SKY65227-11 Intera nFEM achieves outstanding gain
matching which is a critical requirement for MIMO operation. This
is accomplished though mirrored layout symmetry.
The SKY65227-11 is packaged in a lead (Pb)-free, RoHS-compliant
laminate package, which measures 140 mm². This FEM is
designed as a pin to pin compatible version of the SKY65225-11
for 2.4 GHz only.
