Abstract

En bredbåndet, lavstøy, med små frekvenstrinn og faselåst sløyfefrekvenssyntetiserer (10) og fremgangsmåte derved. Syntetisereren (10) Innbefatter en første deler (16) for deling av et første signal tllveiebrakt av en referansefrekvenskllde (12). En første faselåst sløyfe (20) tilveiebringes for å motta et delt første signal fra den første deleren (16) og for å tilveiebringe et mellomfrekvensslgnal som reaksjon derpå. Den første faselåste sløyfen (20) Innbefatter en første fasedetektor (22) for sammenligning av fasen til det første signalet med fasen til det første tllbakekoblingsslgnalet og for å tilveiebringe et første faseforskjellsslgnal som reaksjon derpå. Den første faselåste sløyfen (20) Innbefatter en første spenningsstyrt oscillator (30) for å tilveie- bringe mellomfrekvensslgnalet som reaksjon på det første faseforskjellssignalet. Den første faselåste sløyfen (20) Innbefatter en første blander (32) for å blande mellomfrekvensslgnalet med et andre signal ved en andre frekvens F2 og for å tilveiebringe det første tllbakekoblingsslgnalet som reaksjon derpå. Bi andre deler (38) er anordnet l den første faselåste sløyfen (20) for å dele det første tilbakekoblingssignalet før dets tilførsel til den første fasedetektoren (22). En tredje deler (39) er anordnet for å forskyve frekvensen til mellom- frekvensslgnalet og en andre faselåst sløyfe (40) er koblet til den tredje deleren for behandling av det frekvensskiftede mellomfrekvensslgnalet og for å tilveiebringe et utgangsfrekvenssignal fra syntetisereren. Den andre faselåste sløyfen (40) innbefatter en andre fasedetektor (42) for sammenligning av fasen til det skiftede mellomfrekvenssignalet med fasen til det andre tilbakekoblingssignalet og for å tilveiebringe et andre fasefor- skjellsslgnal som reaksjon derpå. En andre spenningsstyrt oscillator (50) er anordnet for å tilveiebringe utgangsfrekvenssignalet fra syntetisereren 10.
