Attenuator wani nau'i ne na lantarki wanda aka yi amfani dashi sosai a cikin kayan lantarki, kuma babban aikinsa shine samar da attenuation. Abu ne mai cin makamashi, wanda ke juyawa zuwa zafi bayan amfani da wutar lantarki. Babban manufarsa shine: (1) Daidaita girman sigina a cikin kewaye; (2) A cikin da'irar ma'auni na hanyar kwatanta, ana iya amfani da shi don karanta ƙimar ƙima na cibiyar sadarwar da aka gwada; (3) Haɓaka matching impedance, idan wasu da'irori suna buƙatar Lokacin da aka yi amfani da ingantacciyar ma'aunin nauyi mai ƙarfi, ana iya shigar da attenuator tsakanin da'irar da ainihin ma'aunin nauyi don kiyaye canjin impedance. Don haka lokacin amfani da attenuator, menene al'amuran da ke buƙatar kulawa?
Bari mu gabatar da shi daki-daki a kasa:
1. Amsar mitar: bandwidth mita, gabaɗaya ana bayyana a megahertz (MHz) ko gigahertz (GHz). Maƙasudin maƙasudin gabaɗaya gabaɗaya suna da bandwidth na kusan 5 GHz, tare da matsakaicin bandwidth na 50 GHz.
2. Kewayon attenuation da tsarin:
Kewayon attenuation yana nufin rabon attenuation, gabaɗaya daga 3dB, 10dB, 14dB, 20dB, har zuwa 110dB. Tsarin attenuation shine: 10lg (shigarwa / fitarwa), misali: 10dB halayyar: shigarwa: fitarwa = attenuation mahara = 10 sau. Gabaɗaya tsarin ya kasu kashi biyu: ƙayyadadden madaidaicin attenuator da matakin daidaitacce attenuator. Kafaffen attenuator yana nufin attenuator tare da ƙayyadaddun rabo mai yawa a cikin kewayon mitar. Matakai attenuator ne attenuator tare da ƙayyadadden ƙima da daidaitaccen rabo na tsaka-tsaki. An kasu kashi na hannun hannu mataki attenuator da programmable mataki attenuator.
3. Form shugaban haɗin haɗi da girman haɗin haɗi:
An raba nau'in haɗin zuwa nau'in BNC, nau'in N, nau'in TNC, nau'in SMA, nau'in SMC, da sauransu. A lokaci guda, siffar haɗin yana da nau'i biyu: namiji da mace.
An raba girman haɗin kai zuwa tsarin awo da tsarin mulki, kuma an ƙayyade abin da ke sama bisa ga buƙatun amfani; idan ana buƙatar haɗa nau'ikan haɗin kai, ana iya haɗa adaftar haɗin haɗin daidai, misali: mai haɗa nau'in BNC zuwa nau'in N, da sauransu.
4. Fihirisar attenuation:
Alamun attenuation suna da buƙatu da yawa, galibi abubuwan da ke biyowa: daidaiton attenuation, juriya, ƙarfin hali, rashin ƙarfi, aminci, maimaitawa, da sauransu.
Kamar yadda mai zanenattenuators, Jingxin na iya tallafa muku tare da nau'ikan attenuators daban-daban gwargwadon maganin ku na RF.
