SKY65233-11

DATA SHEET SKY65233-11: WLAN 802.11n Single-Band 2.4 GHz 2 x 2 MIMO Intera™ Front-End Module with 3 Antenna Ports Features G G G G G G G G Description The SKY65233-11 Intera nFEM combines two complete 2.4 GHz transmit/receive chains in one compact RF front end module optimized for 2 x 2 MIMO (multiple in—multiple out) operation, in compliance with the 802.11n draft standard. The SKY65233-11 includes two 2 GHz PAs, each with integrated input filtering for 3–4 GHz rejection, and two temperature-compensated, directional power detectors with 20 dB dynamic range. Also included are low loss, high rejection GaAs filters and diversity switches which provide high linearity in all transmit paths and low loss in all receive paths. Additionally, a third antenna port is added to provide switch diversity capability on both chains. All RF ports are matched to 50 Ω. The SKY65233-11 Intera nFEM achieves outstanding gain matching which is a critical requirement for MIMO operation. This is accomplished though mirrored layout symmetry. The SKY65233-11 is packaged in a lead (Pb)-free, RoHS-compliant laminate package, which measures 140 mm2. It is designed as a pin-to-pin compatible version of SKY65230-11 for 2.4 GHz only.
