Load pull

Load pull is when you play with a toy truck and make it go in different directions. Imagine you have a toy truck that has a string attached to it, and you pull the string in different directions to make the truck go where you want it to go.

In the same way, load pull is when people play with circuits in electronics. They use special devices called "load pull tuners" that help them control how much power goes into the circuit and how much comes out.

It's like pulling the string on the toy truck – the load pull tuner helps you control the direction and speed of the electricity going through the circuit. By adjusting the tuner in different ways, you can change the behavior of the circuit and make it work more efficiently.

Overall, load pull is just a fancy way of saying people play with circuits to make them work better, like playing with a toy truck to make it go where you want it to go.
