Patent number: 11336232Abstract: The present disclosure relates to an amplifier arrangement comprising a first amplifier, a second amplifier and an output combiner arranged to combine respective output signals of the first amplifier and the second amplifier into an output signal of the amplifier arrangement. An amplifier arrangement input signal is arranged as input signal to the first amplifier, and a difference signal, representing a difference between the amplifier arrangement input signal and a scaled output signal of the first amplifier, is arranged as input to the second amplifier. The output combiner is arranged to modulate the loads of the first amplifier and the second amplifier in dependence of the output signal of the second amplifier.Type: GrantFiled: May 30, 2018Date of Patent: May 17, 2022Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Mingquan Bao, David Gustafsson, Kristoffer Andersson

Publication number: 20210384636Abstract: There is provided a parallel plate unit cell for a parallel plate arrangement. The parallel plate unit cell comprises a top layer, and a bottom layer. Each of the top layer and the bottom layer has a respective metasurface. The top layer and the bottom layer are arranged in a parallel plate configuration with respect to each other such that the metasurfaces face each other. The top layer and the bottom layer are physically separated by a gap. The gap at least partly is filled with a material having a refractive index n1, where n1>1.2.Type: ApplicationFiled: October 24, 2018Publication date: December 9, 2021Applicant: Telefonaktiebolaget LM Ericsson (publ)Inventors: Oscar QUEVEDO-TERUEL, Martin MATTSSON, Astrid ALGABA BRAZALEZ, Lars MANHOLM, Kristoffer ANDERSSON, Martin JOHANSSON
