Abstract

Oppfinnelsen angår en fremgangsmåte for implementering av transceiver-funksjon i en basestasjon, hvor en effektforsterker forsterker signaler som skal sendes, og en første mottakerforsterker (404) forsterker mottatte signaler, l fremgangsmåten overfører minst to senderenheter (300, 302) i forskjellige sektorer signaler ved forskjellige frekvenser til den samme flerfrekvens-forsterkeren (306) som fungerer som effektforsterkeren; signalene som forsterkes av flerfrekvens-forsterkeren, overføres med en separat kabel (307) fra flerfrekvens-forsterkeren til en filterstruktur (200); filterstrukturen (200) filtrerer minst to signaler som skal sendes ved forskjel- lige frekvenser; sektorspesifikke antenner (318, 320) sender signalene som skal sendes ved forskjellige frekvenser, og mottar signalene som skal mottas ved forskjellige frekvenser; filterstrukturen (200) filtrerer de minst to signalene som mottas ved forskjellige frekvenser; de mottatte signalene filtreres ytterligere med en filterenhet (400), og de filtrerte, mottatte signalene overføres langs en separat kabel (307) fra filterstrukturen (200) via filterenheten (400) til den samme første mottakerforsterkeren (404) som forsterker signalene, hvorpå signalene som mottas fra de forskjellige sektorene, overføres til sektorspesifikke mottakerforsterkere (306, 308).
