Abstract

En digital basebånds- (DBB) mottaker for å ta imot og å prosessere et frådløst kommunikasjonssignal er beskrevet. DBB mottakeren inkluderer i det minste en lavstøyforsterker (LNA), i det minste en demodulator, en likesfrøms- (DC) utiadningskrets og LNA konfrollkrets. LNA forsterker selektivt kommunikasjonssignalet. Demodulatoren sender ut analog, real og imaginærsignalkomponenter på real- og imaginærsignalveiene, respektivt, som svar på mottak av kommunikasjonssignalet fra LNA. DC utladningskretsen utiader selektivt DC som er akkumulert på i det minste en av real- og imaginærsignalveiene. LNA kontiollkretsen skrur LNA på eller av.
