DATA SHEET SKY65228-11: WLAN 802.11n Single Band 4.9–5.85 GHz MIMO Intera™ Front-End Module Features ● ● ● ● ● ● ● ● ● ● ● ● ● 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.
