A quick question: why when designing a cascoded analog amplifier circuit, the major concern is to get the maximum signal transferred, meaning that the output impedance of the previous stage should be small whereas the following stage's input impedance should be large.
When designing a cascoded RF system, the major concern is to get the max power delivery which means the impedance matching.
Why these two senarios require different criteria?
Or more specifically, what kind of chips or circuits should use max power transmission and where should the max voltage transmission be used.
Thank you.
