RF Transceivers .. any suggestions ?

Hello There,

I'm a newbie in using RF modules .. I just purchased the following RF module(TRXQ1):

as I connected it as required by the TRXQ1 data sheet (the connection diagram is shown below)
I would like to ask about things I should take care of for:
1- proper operation with optimal efficiency
2- not damaging the modules.

any recommendations & suggestions are most welcomed ..
thanx for help in advance ;)
cheerz, :D

AYOUB :)
