How to convert ECS-D480A impedance to 50 Ohm system?

hello

I have several ECS-D480A from www.ecaxtal.com

But it have not 50 ohm In/Out impedance ,How Can I convert its impedance to 50 ohm system,please send some help.

from the datasheet , get the input impedance , and convert it real and imaginry , and then match it using the smith chart , it is quite simple

and then verify , the response
