ADAR1000 50ohm termination

Hi. I want to use adar1000 to implement phased array antenna.

When using only the Tx port of the chip, should I connect a 50 ohm resistor to the Rx ports to make a 50 ohm termination?

Or is it possible to open the chip pad because it is internally terminated at 50 ohms?

According to the datasheet, it doesn't seem to be a 50-ohm termination inside the chip.
