How to Connect External power Amplifier to AS3991 RFID reader

Hi Experts,

I have a question I have AS3991 RFID Reader. It has internal PA, It is capalble of reading RFID tags from 30-50 CM. I want to increase the RFID Reader distance upto 80cm-1M, For this i want connect an External PA. Ia this is right or not. If right How we connect this PA to AS3991 Reader. or is there any other choices to increase the reader capacity.

For the connection of External PA, i choose as3991 reader MAAPSS0095 is it right or not.

Expecting a quick reply from you............
