Hi,
I'm trying to understand the device operation.
It is said that its ideal-case efficiency is 50%, i.e. the RF power delivered to the load is half the DC power wasted on the transistor.
My question is, the "load" here is the pull-up resistor connected to the collector? or is it actually the load itself? (which is not shown in the scheme below).
If it's the load itself, how can we promise that the entire RF power will be delivered to the load and will not go to the transistor?
Thank you.
