The FD-5680A specifications say the output is a 0.5 V RMS sine wave into 50 ohms so there are lots of options if that is the signal you want to distribute.
There are a number of medium power operational amplifiers specified for video applications which will operate at a gain of 2 allowing back termination without signal loss while driving several 50 ohm loads in parallel. Most will be current feedback but there are a few voltage feedback ones as well. If you use low supply voltages, then you will need to watch the input common mode voltage range and output voltage range. AC coupling will make that easy. http://www.linear.com/product/LT1206 This amplifier is lower output current but operated at lower supply voltages as well. I might try it with an emitter follower buffer. http://www.linear.com/product/LT1192 Since you are dealing with just a low level sine wave, a single transistor amplifier for each channel would work fine as well. I would probably convert the sine wave into a logic level square wave and maybe use some 50 ohm interface drivers.
