Envelope tracking (ET) power amplifiers and supply modulators represent a pivotal advance in modern radio frequency (RF) design, particularly for wireless communications. These systems dynamically ...

Envelope tracking technology optimises the efficiency of radio frequency (RF) power amplifiers by dynamically adjusting the supply voltage in accordance with the amplitude envelope of the input signal ...

Envelope tracking is a technique used to enhance the efficiency of a power amplifier used in wireless systems. In some applications, ET can deliver better power efficiency compared to the best ...

In the past two weeks, there have been some really neat product introductions that can greatly enhance Envelope Tracking (ET) viability in RF Power Amplifiers (PAs). The LM3290 with integrated boost ...

To help get more life out of a battery, Texas Instruments introduced an efficient envelope tracking power supply solution to support 3G and 4G LTE multi-mode, multi-band RF power amplifiers used in ...

In just a few years’ time, so many things about wireless communication will be different from the way we know them today. Cellular networks, for example, traditionally made up primarily of larger base ...

Tampa, FL. National Instruments chose the International Microwave Symposium to present several demonstrations, with a particular emphasis on power-amplifier design and test. From a design aspect, the ...
