Abstract

Flerbåndet radiomodul for selektivt å tilføre mottatte signaler i flere frekvensbånd til en lavstøyforsterker gjennom en inngangsimpedanstilpasningskrets ved omkopling av lavstøyforsterkerens driftsmodus består da av en førstetrinns forsterkerenhet som inkluderer flere grunnforsterkere som er parallellkoplet med hverandre, hvor disse grunnforsterkere deler mellom seg en lastimpedans som er forbundet med en kildespenning og en jordet degenereringsimpedans, samt har inngangssignalledninger som felles er koplet til en inngangsimpedanstilpasningskrets, mens en forsterker i et påfølgende trinn hvortil utgangssignaler fra de flere grunnforsterkere blir ført inn i fellesskap på inngangssiden, samt en forspenningsregulerende enhet for etter valg å slå på grunnforsterkerne, hvor da inngangsimpedansen for lavstøyforsterkeren selektivt optimaliseres for tilpasningskretsen i avhengighet av det radiofrekvensbånd som skal mottas.
