Hi,
I'm looking for a circuit that is called "RF clamp", "RF limiter", "voltage clamp" or "voltage limiter".
The example of such circuit is a transistor Q on this picture:

I cannot find many of such circuits. Often, they are stacked diodes on antenna lines or diodes + resistor to bias transistor clamp.
Do you know where I could find good examples? Any books, websites?
