Product Summary
The SKY65225-12 is a WLAN 802.11n 2 x 2 MIMO Intera Front-End Module combines two complete dual-band 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 SKY65225-12 includes two 5 GHz PAs and two 2 GHz PAs, each with integrated input filtering for 3–4 GHz rejection, and two temperaturecompensated, directional power detectors with 20 dB dynamic range.
