Determine power reflection coefficient at the input port:
For the MESFET equivalent circuit shown below, find S11 and S22. Note that resistances associated with the voltage-controlled current source are so large, they can be neglected.
What is the power reflection coefficient at the input port? What is S12? Why?
If the input had to be matched using a single lumped element, what would it be, and would it be series or shunt?
