FPD-Link: can I use a RF switch to switch the input of a FPD-Link receiver between two FPD-Link sources?

As the title says I want to have one FPD-Link receiver and two FPD-Link sources. I want to switch between the two inputs. Can I use a RF switch to do so? If so, what are the frequencies the RF switch should operate at? What's the minimum passband frequency required?

    Hi,
    For such solution, pls make sure both FC signal and BC signal can be transmitted through this MUX, you can:
    1. bandpass width: 1MHz ~ Line rate x3
    2. pls evaluate the total link loss and the additive jitter of this MUX. generally it would be much better (more margin) if the system cable is short and PCLK is low.
