RF communication module 400-410 MHz.

Hi

Can anybody help me to find out right communication module form my new project with similar specification as given below:

1. Operating frequency 400-410 MHz
2. Interfacing with microcontroller by UART/SPI
3. With FSK modulation
4. Optional gain or provision for the same by changing antenna of different gain.

I try to get module form http://www.sunrayrf.com/upimages/2010111111436866.pdf but they stopped manufacturing.

If anybody knows any other module with similar specification please send me link or suggest other ideas. I am not good at developing such kind of module independently :(

Thanks

Modules are a lot. Try these HopeRF http://www.hoperf.com/rf/, if you like Chinese. If not, here http://www.semtech.com/images/datash...3f_ag_0108.pdf
from Swiss land.

Thanks Bob60 for you reply.

But i am looking for specific frequency that is between 400-410 MHz. In the model you have suggested are not available in my requirement band. And i have to use the same band because of some restriction for particular field.

Thanks

Hope RF modules can be used if you change the crystal. A lot of small radio transceiver chips are covering the requested frequency range by design. A 430 MHz module based on TI CC1101 should usually work for your band (not considering possible firmware restrictions). Retuning the antenna matching network would improve the output power, however.
