RF load-Pull question in RF PA design

This is the data of a load pull analysis on a phemt transistor I plan on using in a high frequency 50-ohm PA design. it is biased for 6-volt operation. My teacher told me I need to design the input matching network first based on maximum Pdel data. From the load pull information in order to begin the input match. What is the input impedance I am matching, and what must I do first to the Zin impedance as noted on the load pull diagram before starting the input match to the transistor.
