Ama-Attenuator e-PIM aphansi e-RF Microwave Millimeter Wave mm wave
Ama-Attenuator aphansi e-PIM angama-RF kanye nama-microwave signal attenuator aklanyelwe ngokukhethekile ukunciphisa umphumela we-passive intermodulation (PIM). Umphumela we-PIM ubhekisela ezingxenyeni ezengeziwe zemvamisa ezikhiqizwa ngenxa yemiphumela engeyona eqondile ezingxenyeni ezingasebenzi. Lezi zingxenye zizophazamisa isignali yokuqala futhi zinciphise ukusebenza kohlelo.
Inhloso:
1. Ukuncishiswa Kwesignali: Ama-attenuator aphansi e-PIM asetshenziselwa ukunciphisa ngokunembile amandla esignali ye-RF kanye ne-microwave ukuvikela imishini yokwamukela ebucayi kanye namazinga esignali yokulawula.
2. Nciphisa Umphumela Wokushintshashintsha Okungasebenzisi (i-PIM): Ama-attenuator aphansi e-PIM anciphisa umphumela we-PIM ngokusebenzisa izinto ezisezingeni eliphezulu kanye nezinqubo zokukhiqiza ezinembile ukunciphisa imiphumela engeyona eqondile ezingxenyeni ezingasebenzi.
3. Ukumelana Okufanayo: I-attenuator ye-PIM RF ephansi ingasetshenziswa ukufanisa ukungalingani kohlelo, ngaleyo ndlela inciphise ukubonakaliswa namagagasi amile futhi ithuthukise ukusebenza kohlelo.
Isicelo:
1. Isiteshi Sokuxhumana Kwamaselula: Eziteshini zokuxhumana kwamaselula, kusetshenziswa ama-attenuator e-PIM microwave aphansi ukunciphisa umphumela we-PIM, ngaleyo ndlela kuthuthukiswe ukucaca kwesignali kanye nokuthembeka kwezixhumanisi zokuxhumana. Lokhu kubaluleke kakhulu kumanethiwekhi e-4G kanye ne-5G.
2. Uhlelo lwe-Antenna: Kuhlelo lwe-antenna, i-attenuator yamagagasi e-PIM millimeter ephansi isetshenziswa ukunciphisa umphumela we-PIM nokuthuthukisa ukusebenza kanye nekhwalithi yesignali ye-antenna. Lokhu kusiza ukuthuthukisa ukumbozwa kanye namazinga okudluliswa kwedatha kwezinhlelo zokuxhumana.
3. Uhlelo Lwe-Antenna Olusabalalisiwe (i-DAS): Ezinhlelweni ze-antenna ezisabalalisiwe, ama-attenuator aphansi e-PIM mm asetshenziswa ukunciphisa imiphumela ye-PIM, ngaleyo ndlela kuthuthukiswe ukusebenza kwesistimu kanye nokuthembeka. Lokhu kubaluleke kakhulu ezixazululweni zokumboza okungenantambo zangaphakathi nangaphandle.
4. Ukuhlolwa kwe-Microwave ne-RF: Ezinhlelweni zokuhlola ze-microwave ne-RF, ama-attenuator aphansi e-PIM RF asetshenziswa ukulawula ngokunembile amandla esignali nokunciphisa imiphumela ye-PIM yokuhlolwa nokulinganisa okunembe kakhulu.
5. Umsakazo ne-TV: Ezinhlelweni zomsakazo ne-TV, ama-attenuator aphansi e-PIM asetshenziswa ukunciphisa imiphumela ye-PIM nokuthuthukisa ikhwalithi yesignali kanye nokumbozwa kwayo. Lokhu kusiza ekuhlinzekeni amasignali omsindo nevidiyo acacile.
6. Ukuxhumana Ngesathelayithi: Ezinhlelweni zokuxhumana ngesathelayithi, ama-attenuator aphansi e-PIM asetshenziswa ukunciphisa imiphumela ye-PIM nokuthuthukisa ukuthembeka kanye nekhwalithi yesignali yezixhumanisi zokuxhumana. Lokhu kubaluleke kakhulu ekuxhumaneni ngesathelayithi okuvamise kakhulu.
Ngamafuphi, ama-attenuator aphansi angasebenzi kahle (ama-Low PIM Attenuators) asetshenziswa kabanzi emikhakheni eminingi efana nokuxhumana kwamaselula, izinhlelo ze-antenna, izinhlelo ze-antenna ezisatshalaliswayo, ukuhlolwa kwe-microwave kanye ne-RF, umsakazo nethelevishini, kanye nokuxhumana kwesathelayithi. Athuthukisa ukusebenza kohlelo kanye nokuthembeka ngokunciphisa imiphumela ye-PIM kanye nokulawula ngokunembile amandla esignali.
I-QualwaveIhlinzeka ngokunemba okuphezulu okuhlukahlukene kanye ne-coaxial enamandla aphezulu Ama-Attenuator aphansi e-PIM amboza ububanzi bemvamisa DC~11GHz. Ukuphathwa kwamandla okumaphakathi kungafika kuma-watts angu-300. Ama-attenuator asetshenziswa ezindaweni eziningi lapho kudingeka khona ukunciphisa amandla.
