I-Attenuator yinxalenye ye-elektroniki esetyenziswa ngokubanzi kwizixhobo zombane, kwaye umsebenzi wayo oyintloko kukubonelela ngokunciphisa. Yinto edla amandla, ejika ibe bubushushu emva kokusetyenziswa kwamandla. Iinjongo zayo eziphambili zezi: (1) Lungisa ubungakanani bomqondiso kwisiphaluka; (2) Kwisekethe yokulinganisa indlela yokuthelekisa, ingasetyenziselwa ukufunda ngokuthe ngqo ixabiso lokunciphisa umnatha ovavanyiweyo; (3) Ukuphucula ukulinganisa i-impedance, ukuba ezinye iisekethe zifuna Xa kusetyenziswa i-impedance yomthwalo ozinzileyo, i-attenuator inokufakwa phakathi kwesekethe kunye ne-impedance yokwenyani yomthwalo ukuze ithintele utshintsho lwe-impedance. Ke xa usebenzisa isithinteli, yeyiphi imiba efuna ingqalelo?
Masiyazise ngokweenkcukacha ngezantsi:
1. Impendulo yamatyeli: i-frequency bandwidth, ebonakaliswa ngokubanzi nge-megahertz (MHz) okanye igigahertz (GHz). Izithinteli zenjongo ngokubanzi ziqhele ukuba ne-bandwidth emalunga ne-5 GHz, kunye ne-bandwidth ephezulu ye-50 GHz.
2. Uluhlu lokuthothisa kunye nesakhiwo:
Uluhlu lwe-attenuation lubhekiselele kumlinganiselo wokuthotywa, ngokubanzi ukusuka kwi-3dB, 10dB, 14dB, 20dB, ukuya kwi-110dB. I-formula yokunciphisa: 10lg (igalelo / imveliso), umzekelo: i-10dB yeempawu: igalelo: i-output = i-attenuation multiple = amaxesha angama-10. Ulwakhiwo ngokubanzi lwahlulahlulwe lwaziintlobo ezimbini: isisithinteli esisisigxina esisisigxina kunye nenyathelo lesithinteli esilungelelanisiweyo. I-Fixed attenuator ibhekiselele kwi-attenuator enomlinganiselo osisigxina ophindaphindiweyo kuluhlu oluthile lwamaza. I-Step attenuator yi-attenuator enexabiso elithile elizinzileyo kunye nomlinganiselo olinganayo wekhefu lokulungelelanisa. Yahlulahlulwe yaba sisithinteli senyathelo lesandla kunye nesithinteli esinocwangciso.
3. Ifom yentloko yoqhagamshelo kunye nobukhulu boqhagamshelwano:
Uhlobo lwe-connector luhlukaniswe ngohlobo lwe-BNC, uhlobo lwe-N, uhlobo lwe-TNC, uhlobo lwe-SMA, uhlobo lwe-SMC, njl. Ngelo xesha, umzobo wokudibanisa uneentlobo ezimbini: indoda nebhinqa.
Ubungakanani bokudibanisa buhlulwe kwii-metric kunye neenkqubo zobukhosi, kwaye oku ngasentla kuchongwa ngokweemfuno zokusetyenziswa; ukuba iintlobo zokudibanisa kufuneka zidibaniswe, i-adapters yokudibanisa ehambelanayo inokuxhotyiswa, umzekelo: i-BNC ukuya kwi-N-type connector, njl.
4. Isalathisi sokuthotywa:
Izalathi zokuthomalalisa zineemfuno ezininzi, ubukhulu becala le miba ilandelayo: ukuchaneka kokuthomalalisa, ukumelana namandla, ukuphazamiseka kweempawu, ukuthembeka, ukuphinda-phinda, njl.
Njengomyili weabancedisi, i-Jingxin inokukuxhasa ngeentlobo ezahlukeneyo ze-attenuators ngokwesisombululo sakho seRF.
