TS'ELISO HONA

Voltage controlled oscillator (VCO) ke oscillator ea elektroniki eo maqhubu a eona a hlahisoang a ka laoloang ke lets'oao la motlakase.

E na le litšobotsi tse latelang:

1. Ho feto-fetoha ha maqhubu: Maqhubu a VCO a ka fetoloa ka ho laola motlakase oa ho kenya letsoho, kahoo o etsa hore maqhubu a eona a phahamisoe ka har'a mefuta e itseng.
2. Ho nepahala ha maqhubu a phahameng: VCO ka tloaelo e na le ho nepahala ha maqhubu a phahameng le botsitso, 'me e ka sebelisoa lits'ebetsong tse hlokang ho nepahala le botsitso bo phahameng.
3. Broadband: VCO e na le mefuta e mengata ea maqhubu a ts'ebetso 'me e ka sebelisoa lits'ebetsong tse fapaneng tse kang puisano ea mohala le lisebelisoa tsa RF.
4. Bokhoni ba ho fetola ka potlako: VCO e na le bokhoni ba ho fetola ka potlako khafetsa, e ka sebelisoang ho finyella mesebetsi e kang ho potlaka ha maqhubu le ho kopanya maqhubu.

Libaka tsa ts'ebeliso ea eona ke tse latelang:

1. Puisano e se nang mohala: VCO e atisa ho sebelisoa mekhoeng ea puisano e se nang mohala, joalo ka puisano ea mehala, puisano ea sathelaete, khaso ea seea-le-moea, joalo-joalo, ho hlahisa maqhubu a sephethephethe sa mats'oao a waelese.
2. Clock le frequency synthesis: VCO e ka sebelisoa e le jenereithara ea oache bakeng sa taolo ea nako le tlhahiso ea matšoao a oache lisebelisoa tsa elektroniki. Ntle le moo, li-VCO tse ngata li ka etsoa khafetsa ka "phase locked loop" (PLL) ho hlahisa matšoao a tsitsitseng maemong a holimo.
3. Teko le tekanyo: VCO e ka sebelisoa bakeng sa lisebelisoa tsa ho hlahloba le ho lekanya, tse kang meter frequency, Spectrum analyzer, joalo-joalo Ka ho fetola motlakase oa ho kenya letsoho, lipontšo tse fapaneng tsa tlhahlobo ea maqhubu li ka hlahisoa.
4. Radar le Navigation Systems: VCO e sebelisoa haholo ho radar le tsamaiso ea ho tsamaea ho hlahisa maqhubu a carriers bakeng sa lipontšo tsa maqhubu a seea-le-moea le ho finyella sepheo sa ho lemoha le ho beha maemo.
5. Lisebelisoa tsa li-audio le video: VCO e ka sebelisoa ho li-audio synthesizers le li-synthesizers tsa lipontšo tsa video ho hlahisa maqhubu a molumo oa molumo le video.

Ka kakaretso, li-oscillator tse laoloang ke motlakase li na le ho feto-fetoha ha maqhubu, ho nepahala ha maqhubu a phahameng, ho nepahala ha maqhubu a mangata, li-broadband, le bokhoni ba ho fetola ka potlako, ho etsa hore li tšoanelehe bakeng sa puisano e se nang thelefono, li-clock le frequency synthesis, liteko le tekanyo, lisebelisoa tsa radar le tsa ho tsamaea, hammoho le lisebelisoa tsa molumo le video masimo a mang.

Qualwavee fana ka VCO ka maqhubu a ho fihla ho 20GHz. Li-VCO tsa rona li sebelisoa haholo libakeng tse ngata.
