ISigaba esiTyelwe ii-Oscillator eziLawulwayo zeVoltage

I-Phase Locked Voltage Controlled Oscillators, luhlobo lwe-frequency synthesizer esebenzisa i-loop-locked loop ukuvala i-frequency output kwi-signal reference. I-oscillator elawulwa yi-voltage (VCO) isetyenziselwa ukuvelisa i-frequency output, ngelixa i-loop-locked loop (PLL) isetyenziselwa ukulawula isigaba kunye nokuphindaphinda komqondiso wokuphuma.

Iimpawu zayo ziquka:

1. Uzinzo oluphezulu lwefrikhwensi:
I-PLVCO inozinzo oluphezulu kakhulu lwe-frequency, kunye ne-loop evaliweyo yesigaba esinokuphelisa utshintsho lwesigaba kunye nokuphazamiseka kwengxolo kwisignali yokufaka, okubangelwa ukuzinza okuphezulu kwemveliso.
2. Uluhlu olubanzi oluhlengahlengiswayo:
I-PLVCO inoluhlu olubanzi oluhlengahlengiswayo, kwaye i-frequency yemveliso inokulungelelaniswa phakathi koluhlu oluthile ngokulawula i-voltage.
3. Inqanaba eliphantsi lengxolo:
I-PLVCO inengxolo yesigaba esiphantsi kakhulu, iyenza ilungele izicelo ezineemfuno zenqanaba eliphezulu, ezinjengonxibelelwano, irada, kunye nezinye iinkalo.
4. Uxhathiso olunamandla lwengxolo:
I-PLVCO inamandla okumelana nengxolo kwaye inokufikelela kwimveliso ethembekileyo ezinzileyo kwiindawo ezinengxolo ephezulu.
5. Ukusebenza ngokukhawuleza okugqwesileyo:
Xa i-frequency ye-input signal okanye isigaba sitshintsha, i-PLVCO inesantya sokuphendula ngokukhawuleza kwaye inokulandelela ngokukhawuleza utshintsho lwesignali yegalelo; Ngexesha elifanayo, isignali yayo yokuphuma nayo inokuphakama okuphezulu kunye nexesha lokuwa, elifanelekileyo lokutshintsha ngokukhawuleza izicelo.
6. Ubungakanani obuncinci kunye nokusetyenziswa kwamandla aphantsi:
I-PLVCO inomgangatho ophezulu kakhulu wokudibanisa, ubungakanani obuncinci, kwaye ingasetyenziswa kwizixhobo ezincinci zombane. Ngexesha elifanayo, ukusetyenziswa kwayo kwamandla kuphantsi kakhulu, kufanelekileyo kwiinkqubo zebhetri.

Isicelo:

1. Inethiwekhi ye-PLL: I-PLVCO ingasetyenziselwa ukuvelisa iimpawu zereferensi kwi-PLL (i-Phase Locked Loop) inethiwekhi.
2. Inkqubo yonxibelelwano: I-PLVCO isetyenziswa ngokubanzi kwiinkqubo ezahlukeneyo zonxibelelwano, ezifana nomabonakude wedijithali, iimodem, neetransceivers zerediyo.
3. Uvavanyo kunye nomlinganiselo: I-PLVCO ingasetyenziswa kwiimvavanyo ezahlukeneyo kunye nezixhobo zokulinganisa, ezifana ne-spectrum analyzer, imitha ye-frequency kunye ne-frequency standard.
4. I-Radar: I-PLVCO ingasetyenziselwa kwiinkqubo ezahlukeneyo ze-radar, ezifana ne-radar-frequency radar, i-radar yokungena emhlabeni, kunye ne-radar yemozulu.
5. Ukuhamba: I-PLVCO ingasetyenziswa kwiinkqubo ezahlukeneyo zokuhamba, kuquka i-GPS, i-GLONASS, i-Beidou, ne-Galileo.

Qualwaveibonelela ngesigaba sesalathiso sangaphandle esitshixayo ii-oscillator ezilawulwayo zombane kunye nesigaba sesalathiso sangaphakathi esitshixiwe ii-oscillator zombane ezilawulwayo, ii-PLVCOs kumaza ukuya kuma-32 GHz.
