“…Because the observed load-pull impedance at output stage of class F PA varies as variance of envelope in envelope tracking circuit, the PAE is decreasing from the maximum point [4,5]. Lastly, using this technique yields both enhancement of PAE and linearity of EER transmitter [6,7]. In this article, we examine the variance of PAE by using harmonic trap for class F PA.…”

“…More details about these techniques will be provided in future sections. Furthermore, in order to enhance the back-off efficiency issue in the amplification, some strategies were suggested such as Kahn Envelope Elimination and Restoration (EER) [1],…”

“…Besides, all the major challenges for practical realization of EER RF PAs are outlined in Fig 1 .6. More information is described in [63], [1], [2], [64], [65], and [66]. The difference between this technique and EER is that the RF input signal contains both amplitude and phase information.…”
