CC1120 Strange output on the spectrum analyzer

Hi,

I am working on building a VHF radio to go on an a CubeSat with a university design team. We built a PCB that uses the CC1120 as the trancsceiver. It is supposed to transmit at 135MHz. We referenced our design off of the 169MHz reference design on the TI website ( http://www.ti.com/tool/CC1120EM-169-RD ).

Unfortunately, after a long time testing the board, we were unable to get the correct output. I attached a screen capture of what appears on the spectrum analyzer when we connect it to the RF output.

Any tips/suggestions would be greatly welcome!

Thanks!

Louis
