wow! i'm also making a transceiver! but not rf range. just around 2 MHz. try something on zigbee perhaps? although i am not an authority of any sort in that. i'm interested in it myself.
I came to know that many are working for multi-giga range receiver.That can detect a wide range of frequencies.Ex: CDMA,GSM,UMTSetc. Also to release this they are using MEMS components. I think this might direct u towards ur target.
Thanks,
