Ama-Oscillator Alawulwa Yi-Voltage Ekhiyiwe Ngesigaba

Ama-Phase Locked Voltage Controlled Oscillators, uhlobo lwe-frequency synthesizer olusebenzisa i-phase-locked loop ukukhiya imvamisa yokuphuma kusignali yokubhekisela. I-voltage-controlled oscillator (VCO) isetshenziselwa ukukhiqiza imvamisa yokuphuma, kuyilapho i-phase-locked loop (PLL) isetshenziselwa ukulawula isigaba kanye nemvamisa yesignali yokuphuma.

Izici zayo zifaka:

1. Ukuqina kwemvamisa ephezulu:
I-PLVCO inokuqina okuphezulu kakhulu kwemvamisa, ene-phase-locked loop engasusa izinguquko zesigaba kanye nokuphazamiseka komsindo esignalini yokufaka, okuholela ekuqineni kwemvamisa ephezulu komphumela.
2. Ububanzi obulungisekayo bemvamisa ebanzi:
I-PLVCO inobubanzi obulungisekayo bemvamisa ebanzi, futhi imvamisa yokukhipha ingalungiswa ngaphakathi kobubanzi obuthile ngokulawula i-voltage.
3. Umsindo wesigaba ophansi:
I-PLVCO inomsindo wesigaba ophansi kakhulu, okwenza ifaneleke ezinhlelweni zokusebenza ezinezidingo zesigaba esiphezulu, njengokuxhumana, i-radar, nezinye izinkambu.
4. Ukumelana nomsindo okunamandla:
I-PLVCO inokumelana nomsindo okuqinile futhi ingafinyelela umphumela ozinzile wemvamisa othembekile ezindaweni ezinomsindo ophezulu.
5. Ukusebenza okusheshayo okuhle kakhulu:
Uma imvamisa yesignali yokufaka noma isigaba sishintsha, i-PLVCO inesivinini sokuphendula esisheshayo futhi ingalandelela ngokushesha izinguquko zesignali yokufaka; Ngesikhathi esifanayo, isignali yayo yokukhipha nayo inesikhathi sokukhuphuka nokuwa okuphezulu, esifanele izinhlelo zokusebenza zokushintsha okusheshayo.
6. Usayizi omncane kanye nokusetshenziswa kwamandla okuphansi:
I-PLVCO inezinga eliphezulu kakhulu lokuhlanganiswa, inosayizi omncane, futhi ingasetshenziswa kumadivayisi amancane kagesi. Ngesikhathi esifanayo, ukusetshenziswa kwayo kwamandla nakho kuphansi kakhulu, kufanelekile ezinhlelweni ezisebenzisa ibhethri.

Isicelo:

1. Inethiwekhi ye-PLL: I-PLVCO ingasetshenziswa ukukhiqiza amasignali okubhekisela kumanethiwekhi e-PLL (Phase Locked Loop).
2. Uhlelo lokuxhumana: I-PLVCO isetshenziswa kabanzi ezinhlelweni zokuxhumana ezahlukahlukene, njengethelevishini yedijithali, amamodemu, kanye nama-transceivers omsakazo.
3. Ukuhlolwa nokulinganiswa: I-PLVCO ingasetshenziswa emishinini eyahlukene yokuhlola nokulinganisa, njenge-spectrum analyzer, imitha yemvamisa kanye ne-frequency standard.
4. I-Radar: I-PLVCO ingasetshenziswa ezinhlelweni ezahlukene ze-radar, njenge-radar evamise kakhulu, i-radar engenela phansi, kanye ne-radar yesimo sezulu.
5. Ukuzulazula: I-PLVCO ingasetshenziswa ezinhlelweni ezahlukene zokuzulazula, okuhlanganisa i-GPS, i-GLONASS, i-Beidou, kanye ne-Galileo.

I-Qualwaveinikeza ama-oscillator alawulwa yi-voltage ekhiyiwe yesigaba sangaphandle kanye nama-oscillator alawulwa yi-voltage ekhiyiwe yesigaba sangaphakathi, ama-PLVCO kumafrikhwensi afinyelela ku-32 GHz.
