Abstract

Fremgangsmåte og anordning for dynamisk justering av impedansen mellom en senders effektforsterker (PA) og antennen for å overføre effekt fra PA til antennen på effektiv mate. Impedansen mellom PA og antennen justeres på grunnlag av effektmåling og/eller PA- likesfrømsforbruksmålinger (DC-forbruksmålinger), avhengig av hvorvidt PA er en lineær-PA eller en svitsjmodus-PA. 1 en annen legemhggjøring implementeres en hybrid-PA som inkluderer en første trinns lineær-PA og en andre trinns svitsjmodus-PH i en sender. Denne hybrid-PA forbinder på selektivt vis utgangen fra den første trinns lineær-PA til en av inngangene til den andre trinns svitsjmodus-PA og utgangen fra hybrid-PA, avhengig av utgangseflekten fra førstetrinns lineær- PA, utgangsnivået fra hybrid-PA, eller et krav som er indikert fra en sendereffekt styringskommando (TPC-kommando).
