HMC877, HMC911 for RF time delay module

Question

Hello. I am trying to use hmc911 or hmc877 chip as time delay in RF line in Ku band phased array antenna. 
 I wonder if this plan to utilize these two chips is appropriate for these applications. 
 Also, the above two chips basically have the RF stage designed as a differential input/output, 
 If I want to use this chip as a single-ended, is it OK terminating the other pad with 50 ohms and using single pair of in/out pads? 
 Thank you very much in advance for the reply.

You may use these chips single ended as well. 
 
 Unused RF input/output pins can be terminated with 50ohms to Vcc directly. 
 Alternatively they can be terminated with 50ohms and a DC block capacitor to the ground.)
