XHUMANA MANJE

Ama-PIM Attenuators aphansi ama-RF kanye nezibambisi zesiginali ye-microwave eziklanyelwe ngokukhethekile ukunciphisa umphumela we-passive intermodulation (PIM). Umphumela we-PIM ubhekisela ezingxenyeni zemvamisa eyengeziwe ezikhiqizwa ngenxa yemiphumela engaqondile ezingxenyeni ze-passive. Lezi zingxenye zizophazamisa isignali yokuqala futhi zinciphise ukusebenza kwesistimu.

Inhloso:

1. Ukunakwa Kwesiginali: Izibambisi ze-PIM eziphansi zisetshenziselwa ukunciphisa ngokunembile amandla amasiginali e-RF nama-microwave ukuze kuvikelwe amathuluzi okwamukela azwelayo kanye namazinga esignali okulawula.
2. Yehlisa I-Passive Intermodulation (PIM) Umphumela: Izibambisi ze-PIM eziphansi zinciphisa umphumela we-PIM ngokusebenzisa izinto zekhwalithi ephezulu kanye nezinqubo zokukhiqiza ezinembile ukuze kuncishiswe imiphumela engaqondile ezingxenyeni ze-passive.
3. I-Impedance Efanisayo: Isibambisi se-PIM esiphansi singasetshenziswa ukufanisa i-impedance yesistimu, ngaleyo ndlela kuncishiswe ukubonakaliswa namagagasi amile futhi kuthuthukise ukusebenza kwesistimu.

Isicelo:

1. Isizinda Sokuxhumana Kwamaselula: Eziteshini eziyisisekelo zokuxhumana kwamaselula, izibambisi ze-PIM eziphansi zisetshenziselwa ukunciphisa umphumela we-PIM, ngaleyo ndlela kuthuthukiswe ukucaca kwesignali nokuthembeka kwesixhumanisi sokuxhumana. Lokhu kubaluleke kakhulu kumanethiwekhi e-4G kanye ne-5G.
2. Uhlelo lwe-antenna: Kuhlelo lwe-antenna, i-PIM attenuator ephansi isetshenziselwa ukunciphisa umphumela we-PIM nokuthuthukisa ukusebenza nekhwalithi yesiginali yothi. Lokhu kusiza ukuthuthukisa amazinga okukhava kanye nokudluliswa kwedatha yezinhlelo zokuxhumana.
3. Isistimu ye-Antenna Esabalalisiwe (DAS): Ezinhlelweni ze-antenna ezisabalalisiwe, izifinyezo eziphansi ze-PIM zisetshenziselwa ukunciphisa imiphumela ye-PIM, ngaleyo ndlela kuthuthukiswe ukusebenza kwesistimu nokuthembeka. Lokhu kubaluleke kakhulu ezisombululweni zokumboza okungenantambo zasendlini nangaphandle.
4. Ukuhlolwa kwe-Microwave ne-RF: Kuzinhlelo zokuhlola ze-microwave ne-RF, izinciphisi ze-PIM eziphansi zisetshenziselwa ukulawula ngokunembile amandla esignali nokunciphisa imiphumela ye-PIM yokuhlolwa nokunemba okuphezulu.
5. Umsakazo ne-TV: Kuzinhlelo zomsakazo kanye ne-TV, izixhumi ze-PIM eziphansi zisetshenziselwa ukunciphisa imiphumela ye-PIM futhi kuthuthukiswe ikhwalithi yesignali nokutholakala. Lokhu kusiza ekunikezeni amasiginali omsindo nevidiyo acacile.
6. Ukuxhumana Ngesathelayithi: Ezinhlelweni zokuxhumana ngesathelayithi, izibambisi ze-PIM eziphansi zisetshenziselwa ukunciphisa imiphumela ye-PIM futhi kuthuthukiswe ukwethembeka kanye nekhwalithi yesignali yezixhumanisi zokuxhumana. Lokhu kubaluleke kakhulu ezokuxhumana ngesathelayithi yamaza aphezulu.
Ngamafuphi, ama-intermodulation attenuators aphansi (I-PIM Attenuators Ephansi) asetshenziswa kabanzi emikhakheni eminingi njengokuxhumana kwamaselula, izinhlelo ze-antenna, izinhlelo ezisabalalisiwe ze-antenna, ukuhlolwa kwe-microwave ne-RF, umsakazo nomabonakude, kanye nezokuxhumana ngesathelayithi. Bathuthukisa ukusebenza kwesistimu nokuthembeka ngokunciphisa imiphumela ye-PIM nokulawula ngokunembile amandla esignali.

Qualwaveinikeza ukunemba okuphezulu okuhlukahlukene namandla aphezulu ama-coaxial I-PIM Attenuators ephansi imboza ibanga lemvamisa DC~1GHz. Isilinganiso sokuphatha amandla singafika ku-150 watts. Ama-attenuators asetshenziswa ezinhlelweni eziningi lapho kudingeka khona ukunciphisa amandla.
