Abstract

Et Doherty-forsterkersystem (1) har flere delforsterkere (2 - 4), hvorav inngangene er styrt via en kontrollenhet (5) med ulike fasevinkler og/eller signalamplituder av et inngangssignal (SI). Ifølge oppfinnelsen er hver utgang av hver delforsterker (2 - 4) koblet direkte til et antenneelement (10 - 12), uten at utgangssignalene fra delforsterkerne (2 - 4) blir kombinert med hverandre før de leveres til antenneelementene (10 - 12). 1
