XHUMANA MANJE

I-Voltage controlled oscillator (VCO) iyi-oscillator ye-elekthronikhi lapho imvamisa yokuphuma kwayo ingalawulwa ngesignali kagesi.

Inezici ezilandelayo:

1. Ukulungiswa kwemvamisa: Imvamisa ye-VCO ingalungiswa ngokulawula i-voltage yokufaka, ngaleyo ndlela yenze ukuguquguquka kwemvamisa yokuphuma kwayo ngaphakathi kwebanga elithile.
2. Ukunemba kwefrikhwensi ephezulu: I-VCO ngokuvamile inokunemba kwefrikhwensi ephezulu nokuzinza, futhi ingasetshenziswa ezinhlelweni ezidinga ukunemba okuphezulu nokuzinza.
3. I-Broadband: I-VCO inobubanzi obubanzi bokusebenza futhi ingasetshenziswa ezinhlelweni ezihlukahlukene ezifana nokuxhumana okungenantambo namasistimu e-RF.
4. Ikhono lokushintsha ngokushesha: I-VCO inamandla okushintsha ngokushesha imvamisa, engasetshenziswa ukuze kuzuzwe imisebenzi efana nokugxuma-gxuma okusheshayo kanye nokuhlanganiswa kwamafrikhwensi.

Izindawo zayo zokufaka isicelo zimi kanje:

1. Ukuxhumana okungenantambo: I-VCO ivamise ukusetshenziswa ezinhlelweni zokuxhumana ezingenantambo, njengokuxhumana kweselula, ukuxhumana ngesathelayithi, ukusakaza ngomsakazo, njll., ukuze kukhiqizwe imvamisa yenkampani yenethiwekhi yamasignali angenantambo.
2. Ukuhlanganiswa kwewashi nemvamisa: I-VCO ingasetshenziswa njengejeneretha yewashi yokulawula isikhathi kanye nokukhiqizwa kwesignali yewashi kumadivayisi kagesi. Ngaphezu kwalokho, ama-VCO amaningi angenziwa imvamisa ngokusebenzisa iluphu evaliwe yesigaba (PLL) ukuze akhiqize amasignali azinzile kumaza aphezulu.
3. Ukuhlola nokulinganisa: I-VCO ingasetshenziselwa ukuhlola nokulinganisa okokusebenza, njengemitha yefrikhwensi, i-Spectrum analyzer, njll. Ngokulungisa i-voltage yokufaka, amasignali okuhlola amafrikhwensi ahlukene angakhiqizwa.
4. I-Radar kanye Nezinhlelo Zokuzulazula: I-VCO isetshenziswa kakhulu kuma-radar namasistimu wokuzulazula ukuze kukhiqizwe amaza okuphatha amasiginali wefrikhwensi yomsakazo futhi kuzuzwe ukutholwa okuhlosiwe kanye nokuma.
5. Imishini yomsindo nevidiyo: I-VCO ingasetshenziswa kuma-synthesizers omsindo nama-synthesizers amasignali wevidiyo ukuze kukhiqizwe imvamisa yamasignali omsindo nevidiyo.

Kafushane, ama-oscillator alawulwa ngama-voltage anokulungiswa kwama-frequency, ukunemba kwefrikhwensi ephezulu, i-broadband, namandla okushintsha ngokushesha, okuwenza afanelekele ukuxhumana okungenantambo, iwashi kanye nokuhlanganiswa kwamafrikhwensi, ukuhlola nokulinganisa, i-radar nezinhlelo zokuhamba, kanye nemishini yokulalelwayo neyevidiyo kanye ezinye izinkambu.

Qualwaveihlinzeka nge-VCO kumafrikhwensi afika ku-20GHz. Ama-VCO ethu asetshenziswa kabanzi ezindaweni eziningi.
