SKY65228-11: WLAN 802.11n Single Band 4.9-5.85 GHz MIMO InteraTM Front-End Module
Features
G G G G G G G G G G G G G
Description
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.
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

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.
