Hi,
Thanks for reply.
Before I posted this message, I had already read this article. This article just gives a general ideal, actually it just mentions how to select components of Analog Devices Inc., and it has nothing to do with circuit design and simulation. Thanks anyway.
I am interested in not only selecting components but also designing and simulation and test circuits. For example, what is the best circuit type of transmitter of commercial medical ultrasound imagining system? RF class E power amp? Or RF class F power amp? Or RF linear amp? Or designer can just use some kind of operational amp because frequency is low (20 MHz or so)? Can anyone (experience engineer) explain this question?
best regards
