WLAN 802.11n 2 x 2 MIMO Front-End Module

The Skyworks SKY65225-11 front-end module combines two complete dual-band transmit/receive chains in one compact RF front-end module optimized for MIMO operation, in compliance with the 802.11n draft standards. SKY65225-11 includes two 5 GHz PAs and two 2 GHz PAs, each with integrated input filtering for 34 GHz rejection, and two temperature compensated, directional power detectors with 20 dB dynamic range. Also included are low loss, high rejection GaAs diplexers and switches which provide high linearity in all transmit paths and low loss in all receive paths. All RF ports are matched to 50 Ohms. The module also achieves outstanding gain matching between both 2 GHz transmit paths and both 5 GHz transmit paths, which is a critical requirement for MIMO operation. The SKY65225-11 is packaged in a lead (Pb)-free, RoHS-compliant laminate package, which measures 140 mm². This tiny footprint enables more functionality in less PCB space.
