Abstract
En basisstasjon i et dupleks radiokommunikasjonssystem omfatter to kombinerte sendere/mottagere (10,12) som hver har en sender (14,20), en hovedmottager (16,22) og en multippel- mottager (18,24). En hovedantenne (26) er forbundet med fellesporten for et første dipleksfilter (38), mens en multippelantenne (28) er forbundet med fellesporten for et andre dipleksfilter (40). En første forsterker og splitter- krets (30,32) mater mottatte hovedsignaler fra hovedantennen (26) til hovedmottagerne (16,22), mens en andre forsterker og splitterkrets (34,36) mater mottatte multippelsignaler fra multippelantennen (28) til multippelmottagerne (18,24). Multippelantennen (28) virker ikke bare som en mottager- antenne, men sender også ut signaler fra senderen (20) slik at mer effekt er tilgjengelig for overføring.
