HMC877, HMC911 for RF time delay module

Thread Summary

The user inquires about using the HMC911 or HMC877 chips for time delay in a Ku band phased array antenna and whether they can be used single-ended. The final answer confirms that these chips can be used single-ended, with unused RF input/output pins terminated with 50 ohms to Vcc or with a 50 ohm resistor and a DC block capacitor to ground.

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.
