CC1110-CC1111: Calculating Transmission Bandwidth

Part Number: CC1110-CC1111

I'm trying to find the transmission bandwidth of the CC1110-CC1111 for -3dB, -20dB, -40dB, -60dB. I'm using a frequency of about 437 MHz, GFSK modulation and 9.6 kbps. I couldn't find anything in the datasheet that could help with figuring out what the transmission bandwidth would be for GFSK. Any help would be great.

    I would recommend measuring it in the lab using a spectrum analyzer. 

    You can also get a fairly accurate number if you set up Matlab to calculate a GFSK signal and calculate the bandwidth according to the graph. The center frequency will not impact the result but the deviation will.
