Chii chinoshanda sefirita yeantenna yemota?
Youdaoplaceholder0 Basa guru refirita reantenna yemotokari nderekudzvinyirira kupindirana kwemagetsi, kuvandudza kunaka kwekutaurirana uye chiyero chesignal-to-noise . Firita inovandudza kuramba kupindirana kwesignal uye chiyero chesignal-to-noise nekubvisa zvikamu zvisingadiwe zvefrequency, nokudaro ichivimbisa kugadzikana uye kuvimbika kwemasisitimu ekutaurirana .
Basa rakati
Youdaoplaceholder0 Dzivisa kupindirana kwemagetsi: Sefa yeantenna yemotokari inogona kuchenesa zvinobudirira kupindirana kwemagetsi, kunyanya masaini ekupindirana kwemagetsi ane frequency yakakwira, kudzivirira kuti asapinde mugrid yemagetsi uye kusvibisa nharaunda yemagetsi. Izvi zvinobatsira kuchengetedza michina yekutaurirana ichishanda zvakanaka uye kudzivirira kukanganiswa kwekutaurirana kana kukanganisa kwedata kunokonzerwa nekupindirana kwemagetsi.
Youdaoplaceholder0 Kuvandudza hunhu hwekutaurirana : Nekusefa masaini ekupindira kwemhepo ane frequency yakakwira, sefa iyi inogona kuvandudza chiyero chesignal-to-noise chemugamuchiri, zvichiita kuti masaini ekutaurirana ajeke uye akasimba. Izvi zvakakosha zvikuru mumidziyo yekutaurirana inoiswa mumotokari, kunyanya munzvimbo dzine ruzha rwakanyanya, izvo zvinogona kuderedza ruzha rwekumashure uye kuvandudza hunhu hwekutaurirana .
Youdaoplaceholder0 Kuvandudzwa kwechiratidzo : Mafirita anobatsirawo kusimudzira kutapurirana kwezviratidzo zvinobatsira, zvichiita kuti zviratidzo zvigadzikane uye zvakarurama zvigamuchirwe pamidziyo yakaita semasisitimu ekufambisa neredhiyo. Izvi ZVAKAKOSHA pakushanda kwakajairika kwesisitimu yekufambisa mota neRADIO .
Dhizaini uye musimboti wekushanda
Mafirita eantenna emotokari anowanzo gadzirwa nema capacitor, inductors uye resistors. Nekushandisa hunhu hwavo hwekupfuura mafrequency akakwira uye kuvhara mafrequency akaderera, vanotungamidza mafrequency akanyanya kupindirana muvhu kana waya isina kupindirana, nokudaro vachiratidza kana kutora masaini ekuvhiringidza. Pamusoro pezvo, firita iyi inogona kudzvinyirira kupindirana kwemagetsi kuburikidza nenzira dzehunyanzvi dzakadai semafirita ematanho akawanda uye circuit yekubhadharisa yekubatanidza kunotungamira .
Youdaoplaceholder0 Sefa yeantenna yemotokari mudziyo unoshandiswa mumasisitimu eantenna emotokari, uyo basa guru nderekusefa masaini asingadiwe kuti ive nechokwadi chekuti antenna inogona kugamuchira masaini anodiwa chete. Mafirita anovandudza kunaka kwechiratidzo chinogamuchirwa uye kugadzikana kwesisitimu nekusarudza mafambiro chaiwo echiratidzo kuti apfuure nepo achidzvanya mamwe mafrequency .
Mhando uye mabasa emafirita eantenna emotokari
Youdaoplaceholder0 Sefa yepasi yakaderera : Inobvumira masaini ari pasi pehuwandu hwakati hwekucheka kuti apfuure uye inovhara masaini ari pamusoro pehuwandu ihwohwo.
Youdaoplaceholder0 Sefa yeHigh-pass : Inovhara masaini ari pasi peimwe cut-off frequency uye inobvumira masaini ari pamusoro pefrequency iyoyo kuti apfuure.
Sefa yebhandi reYoudaoplaceholder0: Inobvumira zviratidzo zvebhandi rimwe kuti zvipfuure nepakati uye inovhara zviratidzo zvemamwe mabhandi.
Sefa yebhendi yeYoudaoplaceholder0: Inovhara masaini kubva kune rimwe bhendi uye inobvumira masaini kubva kune mamwe mabhendi kuti apfuure nepakati.
Maitiro ekushandisa uye kukosha kwemafirita eantenna emotokari
Mafirita eantenna emotokari anoshandiswa zvakanyanya mumasisitimu akasiyana-siyana emagetsi emotokari, kunyanya mumaantenna emotokari eshark fin. Dhizaini iyi haingofadzi chete asi inoderedzawo kudzivirira mhepo. Panguva iyi, firita yakavakirwa mukati inogona kusefa kukanganiswa kwemagetsi kusingakoshi, ichivimbisa kushanda kwakagadzikana kwemidziyo yekutaurirana. Semuenzaniso, mafirita akakosha zvakanyanya muzvikamu zvakakosha zvakaita semasisitimu ekudzora injini nemabhureki kuona kuti masisitimu aya akavimbika uye anovandudza kuchengetedzeka kwekutyaira.
Nheyo yekugadzira uye ma parameter ehunyanzvi emafirita e antenna emotokari
Pfungwa yekugadzira mafirita eantenna emotokari yakavakirwa padzidziso yemagetsi uye dhizaini yedunhu, uye inowanzo umbwa nema capacitor, inductors uye resistors. Maparamita ayo makuru ehunyanzvi anosanganisira frequency yepakati, cut-off frequency, passband bandwidth, insertion loss, ripple, in-band wave, in-band standing wave ratio, return loss, stopband suppression degree, delay uye in-band phase linearity, nezvimwewo. Maparamita aya pamwe chete anosarudza mashandiro uye mhedzisiro yefirita .
Kana uchida kuziva zvakawanda, ramba uchiverenga zvimwe zvinyorwa pane ino saiti!
Ndapota tifonerei kana muchida zvigadzirwa zvakadaro.
Zhuo Meng Shanghai Auto Co., Ltd. yakazvipira kutengesa zvikamu zvemotokari zveMG&750 zvinogamuchirwa Kutenga.
