Yintoni uvavanyo lweRF

1, Yintoni uvavanyo lweRF

IRadio Frequency, edla ngokufinyezwa njengeRF.Uvavanyo lwefrikhwensi kanomathotholo sisishunqulelo samaza ombane wombane atshintshatshintshayo ngoku.Imele i-electromagnetic frequency enokuthi isasaze esithubeni, kunye noluhlu lwamaza ukusuka kwi-300KHz ukuya kwi-110GHz.Ifrikhwensi kanomathotholo, efinyeziweyo njenge-RF, sisishunqulelo samaza ombane wombane atshintshatshintshayo.Ukuphindaphinda kotshintsho olungaphantsi kwamaxesha angama-1000 ngesekondi kubizwa ngokuba yi-low-frequency current, kwaye i-frequency frequency of change more than 10000 times is called high-frequency current.Iifrikhwensi zikanomathotholo loluhlobo lwezandi eziphakamileyo zangoku.

Ukuhanjiswa kwamaxesha axhaphake kuyo yonke indawo, nokuba yi-WI-FI, iBluetooth, iGPS, i-NFC (unxibelelwano olusondeleyo olungenazingcingo), njl., zonke zifuna ukuhanjiswa rhoqo.Kule mihla, itekhnoloji yefrikhwensi yerediyo isetyenziswa kakhulu kwicandelo lonxibelelwano olungenazingcingo, olufana ne-RFID, unxibelelwano lwesikhululo esisisiseko, unxibelelwano ngesathelayithi, njl.

Kwiinkqubo zonxibelelwano ezingenazingcingo, i-RF front-end power amplifiers licandelo elibalulekileyo.Owona msebenzi wayo kukukhulisa imiqondiso yamandla aphantsi kunye nokufumana amandla athile emveliso yeRF.Iimpawu ezingenazingcingo zifumana ukuthomalalisa okubalulekileyo emoyeni.Ukuze kugcinwe umgangatho wenkonzo yonxibelelwano oluzinzile, kuyimfuneko ukukhulisa isignali emoduliweyo kwisayizi enkulu ngokwaneleyo kwaye uyidlulisele kwi-antenna.Ingundoqo weenkqubo zonxibelelwano ezingenazingcingo kwaye imisela umgangatho wenkqubo yonxibelelwano.

2, iindlela zovavanyo lweRF

1. Qhagamshela isahluli samandla usebenzisa intambo ye-RF ngokomzobo ongentla, kwaye ulinganise ilahleko ye-5515C ukuya kwi-EUT ne-EUT kwi-spectrometer usebenzisa umthombo wesignali kunye ne-spectrograph, uze urekhode ixabiso lelahleko.
2. Emva kokulinganisa ilahleko, qhagamshela i-EUT, i-E5515C, kunye ne-spectrograph kumhluli wamandla ngokomzobo, kwaye udibanise isiphelo somhluli wamandla kunye nokunciphisa okukhulu kwi-spectrograph.
3. Lungisa imbuyekezo yenombolo yetshaneli kunye nokulahleka kwendlela kwi-E5515C, kwaye emva koko usethe i-E5515C ngokweeparamitha kwitheyibhile elandelayo.
4. Ukuseka uqhagamshelwano lomnxeba phakathi kwe-EUT kunye ne-E5515C, kwaye emva koko ulungelelanise iiparamitha ze-E5515C kwimowudi yokulawula amandla kuzo zonke iibhithi ukuze i-EUT ikwazi ukuphuma kumandla aphezulu.
5. Misela imbuyekezo yelahleko yendlela kwi-spectrograph, kwaye emva koko uvavanye i-stray eqhutywe ngokwecandelo le-frequency kwitheyibhile elandelayo.Amandla aphezulu ecandelo ngalinye le-spectrum elinganisiweyo kufuneka abe ngaphantsi komda ochazwe kumgangatho wetheyibhile ulandelayo, kwaye idatha elinganisiweyo kufuneka irekhodwe.
6. Emva koko useta kwakhona iiparamitha ze-E5515C ngokwetheyibhile ilandelayo.
7. Ukuseka uqhagamshelo lomnxeba olutsha phakathi kwe-EUT kunye ne-E5515C, kwaye usete iiparamitha ze-E5515C ukuze utshintshe iindlela zokulawula amandla ze-0 kunye ne-1.
8. Ngokwale theyibhile ilandelayo, seta ngokutsha i-spectrograph kwaye uvavanye ilahleko eqhutywe ngokwe-segmentation yamaza.Amandla aphezulu ecandelo ngalinye le-spectrum elilinganisiweyo kufuneka abe ngaphantsi komda ochazwe kumgangatho wetheyibhile ulandelayo, kwaye idatha elinganisiweyo kufuneka irekhodwe.

3, Izixhobo ezifunekayo kuvavanyo lweRF

1. Kwizixhobo zeRF ezingapakishwanga, isikhululo seprobe sisetyenziselwa ukulinganisa, kunye nezixhobo ezifanelekileyo ezifana ne-spectrographs, i-vector network analyzers, iimitha zamandla, iijeneretha zesignali, ii-oscilloscopes, njl. njl.
2. Amacandelo apakishweyo angavavanywa ngokuthe ngqo ngezixhobo, kunye nabahlobo beshishini bamkelekile ukuba banxibelelane.
