Isihlungi se-Band Pass: Ukuguqula Imboni Ye-elekthronikhi

Njengomkhiqizi ohamba phambili wezinto zikagesi, siyaziqhenya ngokwethula izinto ezintsha zakamuva ohlwini lwethu lwemikhiqizo - i Isihlungi se-Band Pass (BPF). Ama-BPF ayizingxenye ze-elekthronikhi ezingasebenzi ezakhelwe ukuvumela ngokukhetha ububanzi obuthile bemvamisa ukuthi budlule, ngenkathi zivimbe ezinye. Kulesi sihloko sebhulogi, sizohlola ukuthi ama-BPF asetshenziswa kanjani embonini ye-elekthronikhi ukudala imikhiqizo engcono nokuthuthukisa ukusebenza.

Kuyini i-Band Pass Filter?

Isihlungi se-Band Pass uhlobo lwesihlungi se-elekthronikhi esivumela ukuthi uhla oluthile lwemvamisa ludlule kusekethe yaso. Lesi sihlungi sicindezela ngenkuthalo yonke imvamisa ngaphandle komkhawulokudonsa ofunekayo, okwenza kube ithuluzi eliphumelelayo lokucubungula isignali. Ukusetshenziswa kwama-BPF embonini ye-elekthronikhi Ama-BPF asetshenziswa ezimbonini eziningi, kufaka phakathi ezokuxhumana ngocingo, umsindo nevidiyo, kanye namadivayisi ezokwelapha.

Nazi izindlela ezibaluleke kakhulu zokusebenzisa ama-BPF embonini yama-elekthronikhi.

Ukuxhumana okungenantambo:Izihlungi ze-Band Pass zivame ukufakwa ezinhlelweni zokuxhumana ezingenantambo, njengezingcingo eziphathwayo, ukuze kugcinwe isignali izinzile. Ama-BPF awusizo kakhulu uma kukhulunywa ngokucindezela amasignali angaphandle kwe-band, okungabangela ukuphazamiseka futhi kunciphise ikhwalithi yesignali.

Umsindo nevidiyo:Izihlungi ze-Band Pass nazo zisetshenziswa ezinhlelweni zomsindo ukuvimbela ububanzi bemvamisa obungadingeki ukuthi budlule. Zenza kube lula ukukhiqizwa komsindo wekhwalithi ephezulu ngaphandle komsindo noma ukuhlanekezela. Ekukhiqizweni kwamavidiyo, ama-BPF aseyadingeka ekukhiqizweni kwezithombe ze-HD. Zenza kube lula ukususa imvamisa engafuneki kanye nama-harmonics ngenkathi kulondolozwa ububanzi obufunwayo.

Amadivayisi ezokwelapha:Ama-BPF aseyizingxenye ezidingekayo kumadivayisi ezokwelapha njengemishini ye-magnetic resonance imaging (MRI). Ngokucindezela amaza angaphandle kobubanzi obufunwayo, adala izithombe ezicacile. Ngokufanayo, asetshenziswa kuma-blood analyzer ukuhlunga amaseli egazi abomvu namhlophe kusampula.

Ekuphetheni, izihlungi ze-Band Pass zingamathuluzi anamandla angathuthukisa ukusebenza kwamadivayisi kagesi. Amandla azo okucindezela amaza angafuneki nokuthuthukisa isilinganiso sesiginali nomsindo kuzenza zibe usizo ezinhlelweni ezahlukahlukene.

Njengomkhiqizi ohamba phambili wezinto zikagesi, siyaziqhenya ngokuhlanganisa lobu buchwepheshe emikhiqizweni yethu ukuze sinikeze amakhasimende ethu ukusebenza kwekhwalithi ephezulu kakhulu. Ukubaluleka kwalo ekuthuthukiseni ukusebenza kwezisekhethi zikagesi kwenza izihlungi ze-Band Pass zibe yingxenye ebalulekile embonini yezinto zikagesi.

I-Microwave ye-Si Chuan Keenlion Ukukhetha okukhulu ekucushweni kwe-narrowband kanye ne-broadband, okuhlanganisa amaza omsindo asukela ku-0.5 kuya ku-50 GHz. Aklanyelwe ukuphatha amandla okufaka asukela ku-10 kuya ku-30 ​​watts ohlelweni lokudlulisa lwe-50-ohm. Kusetshenziswa imiklamo ye-Microstrip noma ye-stripline, futhi ilungiselelwe ukusebenza kahle kakhulu.

Singakwazi futhi yenza ngendlela oyifisayo Isihlungi se-rf Band Pass ngokwezidingo zakho. Ungangena ekhasini lokwenza ngokwezifiso ukuze unikeze imininingwane oyidingayo.
