help for making a wireless transceiver
I want to design a receiver/ transceiver for sending data in a 1Km distance so does any body can intrduce me any IC or chip that has interface with UC and I can use it in my circuit as transceiver ? notice that I know there are several module in the shopping that are ready to use but I want to make by my own and another point I want my transmitter works at a frequency band except FM .

To mention an obvious point, wireless data tranmission devices have to be operated according to the national RF regulations. It's your part to check it to avoid trouble. 1 km reach may be a problem relying on license free frequency bands and respective power limits.
Sub GHz transmitters can be expected to achieve better outreach. You get versatile chips from TI and Hope RF. For radiated power above 10 mW, you may need to add a power amplifier.

thx , but the FM transmitter by 2n2219 is FM kind as I said I don't want to use FM band about that chip is also good but as you know is working on ISM band so don't you think working with this chip be hard ? I want to work in frequency lower like 300Mhz or 400Mhz because i think work at this frequency is so easier than ISM band how is your Idea ?

Thx, sure that I don't have problem with RF regulations bye the way please explain more about your Chips , can you give part number ?
in any way thx for your both help FVM and dear ckshivaram . what's your idea about RFPIC transmitter like rfPIC12C509AG ? you know my problem is , If i use a rfPIC as transmitter how should I detect rf signal which is transmitted by rfPIC ? does any body have idea?
Dear Ckshivaram , I have found a chip that is wireless transceiver it's called TR1001 , but my problem is , I don't know how long is this chip range , and I couldn't find anything related to distance in data sheet so could you do me a favor and guide me ?
Thanks
