Ii-Oscillators eziLawulwa yiVoltage eValiweyo yeSigaba

Ii-Phase Locked Voltage Controlled Oscillators, luhlobo lwe-frequency synthesizer esebenzisa i-phase-locked loop ukutshixa i-output frequency kwisignali yesalathiso. I-voltage-controlled oscillator (VCO) isetyenziselwa ukuvelisa i-output frequency, ngelixa i-phase-locked loop (PLL) isetyenziselwa ukulawula i-phase kunye ne-frequency yesignali ye-output.

Iimpawu zayo ziquka:

1. Uzinzo oluphezulu lwefrikhwensi:
I-PLVCO inozinzo oluphezulu kakhulu lwefrikhwensi, kunye ne-phase-locked loop enokuphelisa utshintsho lwefrikhwensi kunye nokuphazamiseka kwengxolo kwisignali yokufaka, nto leyo ekhokelela ekuzinzeni kwefrikhwensi ephezulu yesiphumo.
2. Uluhlu olubanzi oluhlengahlengiswayo lwefrikhwensi:
I-PLVCO inoluhlu olubanzi oluhlengahlengiswayo lweefrikhwensi, kwaye ifrikhwensi yokuphuma ingalungiswa ngaphakathi koluhlu oluthile ngokulawula i-voltage.
3. Ingxolo yesigaba esiphantsi:
I-PLVCO inomsindo wesigaba ophantsi kakhulu, nto leyo eyenza ukuba ifaneleke kwizicelo ezineemfuno zesigaba esiphezulu, ezinje ngonxibelelwano, i-radar, kunye nezinye iindawo.
4. Ukumelana nengxolo enamandla:
I-PLVCO inokumelana nengxolo enamandla kwaye inokufezekisa imveliso ethembekileyo eqinileyo yefrikhwensi kwiindawo ezinengxolo ephezulu.
5. Ukusebenza ngokukhawuleza okugqwesileyo:
Xa i-frequency yesignali yokufaka okanye isigaba sitshintsha, i-PLVCO inesantya sokuphendula esikhawulezayo kwaye inokulandelela ngokukhawuleza utshintsho lwesignali yokufaka; Kwangaxeshanye, isignali yayo yokuphuma ikwanaso nexesha eliphezulu lokunyuka nokuwa, elifanelekileyo kwizicelo zokutshintsha ngokukhawuleza.
6. Ubungakanani obuncinci kunye nokusetyenziswa kwamandla okuphantsi:
I-PLVCO inomgangatho ophezulu kakhulu wokudibanisa, incinci ngobukhulu, kwaye ingasetyenziswa kwizixhobo ezincinci ze-elektroniki. Kwangaxeshanye, ukusetyenziswa kwayo kwamandla kuphantsi kakhulu, kufanelekile kwiinkqubo ezisebenzisa ibhetri.

Isicelo:

1. Inethiwekhi ye-PLL: I-PLVCO ingasetyenziselwa ukuvelisa imiqondiso yesalathiso kwiinethiwekhi ze-PLL (Phase Locked Loop).
2. Inkqubo yonxibelelwano: I-PLVCO isetyenziswa kakhulu kwiinkqubo ezahlukeneyo zonxibelelwano, ezinje ngethelevishini yedijithali, iimodem, kunye nee-transceivers zerediyo.
3. Uvavanyo kunye nokulinganisa: I-PLVCO ingasetyenziswa kwizixhobo ezahlukeneyo zovavanyo kunye nokulinganisa, ezifana ne-spectrum analyzer, i-frequency meter kunye nomgangatho we-frequency.
4. I-Radar: I-PLVCO ingasetyenziswa kwiinkqubo ezahlukeneyo ze-radar, njenge-radar ephindaphindayo, i-radar engenela emhlabeni, kunye ne-radar yemozulu.
5. Ukuhambahamba: I-PLVCO ingasetyenziswa kwiinkqubo ezahlukeneyo zokuhambahamba, kuquka i-GPS, i-GLONASS, i-Beidou, kunye ne-Galileo.

I-Qualwaveibonelela ngee-oscillators ezilawulwa yi-voltage evaliweyo yesigaba sangaphandle kunye nee-oscillators ezilawulwa yi-voltage evaliweyo yesigaba sangaphakathi, ii-PLVCOs kumaza omoya ukuya kuthi ga kwi-32 GHz.
