Cable driver

(low noise and low distortion application)

I want to buffer a small signal with ADA4817 and then send the output signal through a 50 Ohm coax cable. I put a series 50 Ohm resistor at the output of ADA4817. the cable's length is 1 meter.

signal--->ADA4817---50 ohm----->----------------coax cable-------------------->filter>......


is there any problems? or it's better to translate it using a FDA and then sent it through 2 coax cables (I don't have a suitable STP cable)? can I have any common mode voltage (Vdc) on the cables?
