Converting AD8302 output to real and imaginary values

Hello, I've been using an AD8302 module to try and read the reflection coefficient and phase from different devices under test. From the datasheet I am aware that I get the magnitude ratio as a value in between 0 and 1.8V. I want to convert this magnitude ratio into real and imaginary values which can then be transferred to a touchstone format (.s1p) file to be opened using a smith chart later on. May I know what formula to use to convert the magnitude ratio to complex form using the phase?
