AD831 OUT Pin AC-coupled

Can anyone tell me what is RT and CC for as shown in Figure. 10 of AD831 datasheet? I read it said output pin must be "ac-coupled to the load", so is this a high-pass filter network?

 

Besides, I am inputting 50kHz signal monotone into LO, should I consider the impedance matching as suggested? Will removing it a big problem for my signal?

 

Thanks,
