XHUMANA MANJE

Ukuphela kwe-PIM okuphansi kuyizingxenye ezingasebenzi ezisetshenziswa ezinhlelweni ze-RF kanye nezinhlelo ze-microwave eziklanyelwe ngqo ukunciphisa umphumela we-passive intermodulation (PIM). I-PIM ukuphambuka kwesiginali okubangelwa yizingxenye ezingezona eziqondile noma ukuxhumana okungekuhle, okungathinta kakhulu ukusebenza kwezinhlelo zokuxhumana.

Inhloso:

1. Ukuqedwa Kwesignali: Umthwalo wemvamisa yomsakazo usetshenziselwa ukuqeda imigqa yokudlulisa i-RF kanye ne-microwave ukuvimbela ukubonakaliswa kwesignali kanye nokwakheka kwamagagasi amile, ngaleyo ndlela kuqinisekiswe ukuzinza nokusebenza kohlelo.
2. Ukucindezelwa kwe-PIM: Ukuphela kwe-RF kuklanyelwe ngqo ukunciphisa imiphumela yokushintshashintsha okwenziwayo, ukuqinisekisa ukuthi amazinga e-PIM ohlelweni agcinwa ephansi, ngaleyo ndlela kuthuthukiswe ubumsulwa kanye nekhwalithi yesiginali.
3. Ukulinganisa Isistimu: Ama-terminal wamagagasi e-Millimeter asetshenziselwa ukulinganisa isistimu nokuhlola ukuqinisekisa ukunemba kanye nokuphindaphindwa kwemiphumela yokulinganisa.

Izici:

1. Umthwalo we-PIM ophansi usetshenziswa kakhulu ekuhlolweni nasekulinganisweni kwe-RF, izinhlelo zokulinganisa ze-intermodulation ezingasebenzi, ukulinganisa ama-amplifier noma ama-transmitter anamandla aphezulu, kanye nedivayisi yokulinganisa yabahlaziyi benethiwekhi.

2. Ekuhlolweni nasekulinganisweni kwe-RF, ukuqedwa kwe-PIM ephansi kuqinisekisa ukunemba kokuhlolwa, futhi ngokumunca ama-diaphragm wamandla, kunikeza isiqinisekiso sokulinganisa ngokunembile inkomba ye-intermodulation yezingxenye ezingasebenzi.

3. Kuhlelo lokulinganisa olungenamsebenzi phakathi kwe-intermodulation, ukuphela kwe-PIM ephansi kuxhunywe echwebeni elilodwa ledivayisi evivinywayo ukuqinisekisa inqubekela phambili yokuhlolwa, ngaphandle kwalokho ukuhlolwa akukwazi ukwenziwa.
Ekulinganisweni kwama-amplifier noma ama-transmitter anamandla aphezulu, ukumiswa kwe-Low PIM kusetshenziselwa ukufaka esikhundleni sama-antenna nokumunca wonke amandla okuthwala ukuqinisekisa ukunemba kokulinganisa.
Njengedivayisi yokulinganisa yabahlaziyi benethiwekhi, umthwalo ophansi we-intermodulation ungaqinisekisa ukunemba kokulinganisa.
Ngamafuphi, ukuphela kwe-PIM ephansi kusetshenziswa kabanzi emasimini e-RF kanye nama-microwave, futhi kubalulekile ekuqinisekiseni ukunemba kokuhlolwa nokulinganiswa.

I-QualwaveIhlinzeka ngokuphela kwe-PIM ephansi ngamaza asuka ku-DC kuya ku-0.35GHz, futhi amandla afinyelela ku-200W. Ukuphela kwethu kwe-PIM ephansi kusetshenziswa kabanzi ezindaweni eziningi
