SKY65230-11: WLAN 802.11n 2 X 2 MIMO Intera? Front-End Module With 3 Antenna Ports

The SKY65230-11 Intera nFEM combines two complete dual-band transmit/receive chains in one compact RF front end module optimized for 2 x 2 MIMO (multiple inultiple out) operation, in compliance with the 802.11n draft standard. The SKY65230-11 includes two 5 GHz PAs and two 2 GHz PAs, each with integrated input filtering for 3, GHz rejection, and two temperature- compensated, directional power detectors with 20 dB dynamic range. Also included are low loss, high rejection GaAs diplexers 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 ,. By Skyworks Solutions, Inc.
