Ama-Oscillator Alawulwa Ngesigaba Akhiyiwe Amandla Kagesi

I-Phase Locked Voltage Controlled Oscillators, iwuhlobo lwe-frequency synthesizer esebenzisa iluphu ekhiywe ngesigaba ukukhiya imvamisa yokuphumayo kusiginali yereferensi. I-oscillator elawulwa yi-voltage (VCO) isetshenziselwa ukukhiqiza imvamisa yokuphuma, kuyilapho i-loop evaliwe ngesigaba (PLL) isetshenziselwa ukulawula isigaba nemvamisa yesiginali yokuphumayo.

Izici zayo zihlanganisa:

1. Ukuzinza kwefrikhwensi ephezulu:
I-PLVCO inokuqina okuphezulu kakhulu kwefrikhwensi, eneluphu ekhiywe ngesigaba engasusa izinguquko zesigaba kanye nokuphazamiseka komsindo kusiginali yokufaka, okuholela ekuzinzeni kwemvamisa ephezulu kokuphumayo.
2. Ibanga eliguquguqukayo elibanzi:
I-PLVCO inebanga eliguquguqukayo elibanzi, futhi imvamisa yokuphuma ingalungiswa phakathi kwebanga elithile ngokulawula i-voltage.
3. Umsindo wesigaba esiphansi:
I-PLVCO inomsindo wesigaba esiphansi kakhulu, okwenza ifaneleke izinhlelo zokusebenza ezinezidingo zesigaba esiphakeme, njengokuxhumana, i-radar, nezinye izinkambu.
4. Ukumelana nomsindo okuqinile:
I-PLVCO inokumelana nomsindo oqinile futhi ingafinyelela okukhiphayo okuthembekile okuzinzile 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 yokuphuma nayo inesikhathi sokukhuphuka nokuwa okuphezulu, esilungele izinhlelo zokusebenza zokushintsha ngokushesha.
6. Usayizi omncane kanye nokusetshenziswa kwamandla okuphansi:
I-PLVCO inezinga eliphezulu kakhulu lokuhlanganisa, usayizi omncane, futhi ingasetshenziswa kumadivaysi amancane kagesi. Ngesikhathi esifanayo, ukusetshenziswa kwayo kwamandla nakho kuphansi kakhulu, kulungele izinhlelo ezisebenza ngebhethri.

Isicelo:

1. Inethiwekhi ye-PLL: I-PLVCO ingasetshenziselwa ukukhiqiza amasiginali ayinkomba kumanethiwekhi e-PLL (Isigaba Esikhiyiwe Loop).
2. Uhlelo lwezokuxhumana: I-PLVCO isetshenziswa kakhulu ezinhlelweni zokuxhumana ezahlukahlukene, njengomabonakude wedijithali, amamodemu, nama-transceivers omsakazo.
3. Ukuhlolwa nokulinganisa: I-PLVCO ingasetshenziswa kumishini ehlukahlukene yokuhlola neyokulinganisa, efana ne-spectrum analyzer, imitha yefrikhwensi kanye nesilinganiso samafrikhwensi.
4. I-Radar: I-PLVCO ingasetshenziswa ezinhlelweni ezihlukahlukene ze-radar, njenge-radar yamagagasi aphezulu, i-radar engena emhlabathini, ne-radar yesimo sezulu.
5. Ukuzulazula: I-PLVCO ingasetshenziswa ezinhlelweni ezihlukahlukene zokuzulazula, kuhlanganise ne-GPS, i-GLONASS, i-Beidou, ne-Galileo.

Qualwaveinikeza umsindo wesigaba esiphansi se-PLVCO kumafrikhwensi afika ku-32 GHz.
