Product Summary
The SKY65227-11 is a WLAN 802.11n Single Band MIMO Intera Front-End Module contains two complete 2.4 GHz transmit/receive chains in one compact RF front-end module optimized for single band 2.4 GHz MIMO (multiple in—multiple out) operation, in compliance with the 802.11n draft standard. The SKY65227-11 includes two 2 GHz PAs with integrated input filtering for 3–4 GHz rejection, and temperature-compensated, 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.
