Description
Single band 4.9–5.85 GHz MIMO architecture
Two full 4.9–5.85 GHz transmit/receive chains
Backward-compatible with 802.11a standards
Pin compatible with SKY65225-11 (4.9–5.85 GHz)
POUT @ 2.5% EVM: 16 dBm (-11a)
Gain matching: <2 dB
Internal voltage regulation
Single 3.0–3.6 V power supply
Temperature-compensated PA bias networks
Separate digital controls for each PA
Temperature-compensated directional power detection
Package size: 10 x 14 x 0.9 mm
Lead (Pb)-free and RoHS-compliant MSL-3 @ 250 °C
per JEDEC J-STD-020
The SKY65228-11 Intera nFEM contains two complete
4.9–5.85 GHz transmit/receive chains in one compact RF front-end
module optimized for single band 4.9–5.85 GHz MIMO (multiple
in—multiple out) operation, in compliance with the 802.11n draft
standard. The SKY65228-11 includes two 4.9–5.85 GHz PAs with
integrated input filtering for 3–4 GHz rejection, and temperaturecompensated, 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 SKY65228-11 Intera nFEM achieves outstanding gain
matching which is a critical requirement for MIMO operation.
This is accomplished though mirrored layout symmetry.
The SKY65228-11 is packaged in a lead (Pb)-free, RoHS-compliant
laminate package, which measures 10 x 14 x 0.9 mm. This
FEM is designed as a pin to pin compatible version of the
SKY65225-11 for 4.9–5.85 GHz only.
NEW
Skyworks offers lead (Pb)-free, RoHS (Restriction of
Hazardous Substances)-compliant packaging.

802.11n Operation
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.
