Looking for Up and down RF converter for small UAV

[Ravians]

rf uav

Hello to All
Currently i am working on small UAV communications. I need up and down converter to work with ISM Band (say 430,800 or 960 MHz) with up to few MHz bandwidth.
Plz, anyone can tell me from where i can get preassembled this circuit with cheap rate.
Thanks.

Please clarify your request further:
* What is the application (video streaming I assume)
* Are you sure that your country's regulation allows this bandwidth? I have my certainly doubts about the 433 MHz band
* The communication needs to be set up at what maximum distance? This defines the power budget

Well
1. I have to work only for audio.
2. I need these circuits without the modulation/demodulation circuits.
Thanks.

Then what is your intermediate signal that needs upconverting? Is it a baseband or IF signal, and at what frequency?

I wonder why you need several MHz bandwidth for audio streaming ...

Hi
i make my statement more clear.
for downcoverter

i want output 2 MHz from the A/D converter .

While using the s band or 800 MHz input in converter. So tell me what IF should i used to get 2 MHz from A/D converter.
And also advise me about the sampling technique as well in the A/D converter.

So now i think its much clear. Can you help me regarding this.
