Envelope Tracking Video Tutorial by Radio-Electronics

Envelope Tracking Video Tutorial by Radio-Electronics - RF Cafe

Ian Poole, of the Radio-Electronics website, has produced an excellent video tutorial on the subject of envelope tracking usage in modern radios (aka cellphones). A combination of clear diagrams, interviews with design engineers, and live screen shots of signal behavior is used to effectively illustrate the principles without going into gory mathematical detail. If you have ever wondered why cellphone power amplifier (PA) companies like Qorvo (RFMD), Skyworks, and Peregrine also make and sell DC-DC converter and DC power management ICs, this video will answer the question.
