Dont use AI or Ill Automatically thumbs down!

a$)$ Design a shunt stub tuner circuit to match a load $$ to $50$ Ohms at $800$ MHz where the load is a series connection of a resistor with an inductor where R $=120$ and L$=10$nH$.$ Use an open$-$ended stub. Use $50$ Ohms transmission lines with $=90,$ $=$ $0.$ Draw your circuit indicating the lengths of each section. You need to show only one design. No need for two designs.
