!!!Please note that MMA25312BT1 is not recommended for new designs.
MMA25312BT1 can be turned on/off by switching bias supply (VBA1,VBA2,VBIAS together). Though, this option hasn't been characterized for TDD operation and we can't provide you measured rise/fall time values. I expect switching time to be somewhat less than a microsecond (few hundreds of nsec).
If you do not worry about idle power consumption of MMA25312BT1 then it is more reasonable to use external RF switch at the input port of MMA25312BT1 (SA630 or similar).
Have a great day,
