RF module interfacing with bf5333 problem need help

Dear all hope to be all fine
i need to parches RF section to provide air interface on my blackfin kits bf533 EZkit lite evaluation kits

The only available interface is UART
so we searched about RF section which include UART the problem i found that each RF i found it contain modulation like MSK or 2 FSK but actually i implement Zigbee 802.15.4 protocol no the kit which use oqpsk modulation so when this RF make another modulation this make me have to get another RF part in other side which do the same modulation like this RF

The questions is

1-should RF module contain modulation technique or i can fin RF module front end only and work with my project?

2- if i send signal with this RF module - opearate in ISM band 2.4GHZ- can i recive any signal in this band or shouls the signal from the same part in the other side

Can i recive zigbee signal from zigbee tranciver ?

So please any ont help me to interface my ZIGBEE kit with suitable RF module to recive signal from other RF module
the RF i choose is
http://amber-wireless.de/42-1-AMB2520.html
and i can get its usb compatible part or get zigbee transceiver instead to get the signal from it

sorry for long message and thanks in advance

ohh its about 27 vieew this topics and nothing have any hints ...disappointed
