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: Oscillator e laoloang ke motlakase oa microwave hangata e 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. Tšebeliso ea oache le maqhubu: High Frequency voltage controlled oscillator e ka sebelisoa e le jenereithara ea oache bakeng sa taolo ea nako le tlhahiso ea matšoao a oache lisebelisoa tsa elektroniki. Ho feta moo, li-VCO tse ngata li ka etsoa khafetsa ka "phase locked loop" (PLL) ho hlahisa matšoao a tsitsitseng ka maqhubu a phahameng.
3. Teko le tekanyo: Li-oscillator tse laoloang ke Mm wave voltage li ka sebelisoa bakeng sa lisebelisoa tsa ho hlahloba le ho lekanya, tse kang frequency meter, Spectrum analyzer, joalo-joalo.
4. Radar le Navigation Systems: Mm wave voltage controlled oscillator 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: Li-oscillator tse laoloang ke li-millimeter wave voltage li ka sebelisoa ho li-audio synthesizers le li-synthesizers tsa pontšo ea video ho hlahisa maqhubu a molumo oa molumo le video.

Ka kakaretso, li-oscillator tse laoloang ke motlakase oa rf li na le ho feto-fetoha ha maqhubu, ho nepahala ha maqhubu a phahameng, ho nepahala ha maqhubu a marang-rang, li-broadband le bokhoni ba ho fetola ka potlako, e leng se etsang hore li tšoanelehe bakeng sa puisano e se nang mohala, oache le maqhubu a synthesis, tlhahlobo le tekanyo, lisebelisoa tsa radar le tsa ho tsamaea, hammoho le lisebelisoa tsa molumo le video le likarolo tse ling.

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