How can I change the central frequency of a baseband modulated signal in simulink?

I'm pretty new to simulink and I'm trying to implement a simple digital GFSK mod/demod system that works at 169Mhz.
I've implemented the Tx model (random source at 4kbps and CPFSK with Gaussian Filter), but now I need to bring the signal at 169Mhz. I'm analyzing the spectrum using the Spectrum Analyzer block.
How can I bring the signal to passband 169Mhz and then bring it back to baseband at the receiver?
Thanks. Giuseppe
