What is an RF detector? An RF detector monitors or samples the output of an RF circuit and develops a dc output voltage proportional to the power at that point. What do you do with an RF detector? RF ...

Radio frequency (RF) power amplifiers are all over the place. Some of them can deliver enough RF output power to do biological harm to somebody. Many such amplifiers are solid state, but many others ...

With 14 envelope-tracking-enabled handsets now on the market, and more sets to follow in the coming years, envelope tracking (ET) has been firmly accepted as the industry standard for the architecture ...
