ADRF5040-EVALZ is not working

My name is Usman, I am a PhD student in Chung-Ang University, Seoul, South Korea.

I recently bought ADRF5040-EVALZ RF switch SP4T evaluation board from, a distributor in Seoul, Korea which sells analog devices components.

Today, I tested the evaluation board and it has some problem.

After connecting different voltage levels (0V and 3.3V) to the V1 and V2 pins of evaluation board, the states are not changing. For all the logic, the switch only connects RFC to RF4 only. The other three paths are not working.

I need some help.

Is the board faulty?
