dc.description.abstract	This paper presents a practical application of a method for generating slew-rate limited envelopes in order to drive the dynamic supply of envelope tracking (ET) power amplifiers (PAs). The proposed method results useful to generate slower versions of the transmitted signal’s envelope to cope with the slew-rate and bandwidth limitations of envelope amplifiers. Moreover, this paper shows experimental results comparing the performance of ET when exciting the drain of a PA (based in a GaN transistor) with both the envelope of the signal and the slew-rate limited version of the envelope.
