摘要：
In this contribution, the simulated and measured results of a 2(nd) harmonic tuned power amplifier managed with envelope tracking technique are presented. From experimental results, the bias tracking leads to an average efficiency improvement from 30.6% to 43.6% considering 12dB of input power back-off, with respect to the same power amplifier with fixed bias point. In both cases the same behaviour for output power, which reaches 40.4 dBm, and a constant gain (12.4 dB) has been observed.
