With AD9364 IC, is it possible to implement MIMO using one Frequency 2.4G

AD9364 IC  has  3 differential  receiver , RXA_P, RXA_N,  RXB_P, RXB_N, RXC_P, RXC_N, 

and 2 differential  receiver , TXA_P, TXA_N,  TXB_P, TXB_N.

I would like to construct 2 x 2 MIMO using RXA_P/N , RXB_P/N ,TXA_P/N ,TXB_P/N ,

Is it possible to implement MIMO  using one Frequency ?

Also why AD9364  named RF 1 × 1 transceiver ?  i think  AD9364  RF 2 × 2  transceiver right ?

Thanks .
