Izici:
- Inani eliphakeme kakhulu lama-VSWR
- Inani eliphakeme kakhulu lama-PIM
Izinqamuli ze-PIM eziphansi ziyizingxenye zokungenzi lutho ezisetshenziswa ezinhlelweni ze-RF kanye ne-microwave eziklanyelwe ngokuqondile ukunciphisa umphumela we-passive intermodulation (PIM). I-PIM iwukuhlanekezela kwesignali okubangelwa izingxenye ezingezona ulayini noma abathintwayo abampofu, okungase kuthinte kabi ukusebenza kwezinhlelo zokuxhumana.
1. Ukunqanyulwa Kwesiginali: Ukunqanyulwa kwe-PIM ephansi kusetshenziselwa ukunqamula izintambo zokudlulisa i-RF kanye ne-microwave ukuze kuvinjelwe ukubonakaliswa kwesignali nokwakheka kwamagagasi okuma, ngaleyo ndlela kuqinisekiswe ukuzinza nokusebenza kwesistimu.
2. Ukucindezelwa kwe-PIM: Aklanyelwe ngokuqondile ukunciphisa imiphumela ye-intermodulation ye-passive, ukuqinisekisa ukuthi amazinga e-PIM ohlelweni agcinwa esezingeni eliphansi, ngaleyo ndlela athuthukise ukuhlanzeka nekhwalithi yesiginali.
3. Ukulinganiswa Kwesistimu: Amatheminali e-PIM aphansi asetshenziselwa ukulinganisa uhlelo nokuhlola ukuze kuqinisekiswe ukunemba nokuphindaphindwa kwemiphumela yokulinganisa.
1. Ukunqanyulwa kwe-PIM ephansi kusetshenziswa kakhulu ukuhlola nokulinganisa i-RF, amasistimu okulinganisa okwenziwa kwe-intermodulation, ukukalwa kwezikhulisi zamandla aphezulu noma ama-transmitter, nanjengedivayisi yokulinganisa yabahlaziyi benethiwekhi. .
2. Ekuhloleni nasekukaleni kwe-RF, ukunqanyulwa kwe-PIM ephansi kuqinisekisa ukunemba kokuhlolwa, futhi ngokumunca ama-diaphragm amandla, kunikeza isiqinisekiso sokulinganisa ngokunembile inkomba ye-intermodulation yezingxenye ze-passive.
3. Kusistimu yokulinganisa i-intermodulation ye-passive, ukunqanyulwa kwe-PIM Ephansi kuxhunywe embobeni eyodwa yedivayisi ngaphansi kokuhlolwa ukuze kuqinisekiswe ukuqhubeka kokuhlolwa, ngaphandle kwalokho ukuhlolwa ngeke kwenziwe.
Esilinganisweni sama-amplifiers noma ama-transmitters anamandla aphezulu, ukunqanyulwa kwe-PIM ephansi kusetshenziselwa ukufaka esikhundleni sama-antenna futhi kudonsa wonke amandla enkampani yenethiwekhi ukuze kuqinisekiswe ukunemba kokulinganisa.
Njengedivayisi yokulinganisa yabahlaziyi benethiwekhi, umthwalo we-intermodulation ophansi ungaqinisekisa ukunemba kokulinganisa.
Kafushane, ukunqanyulwa kwe-PIM ephansi kusetshenziswa kakhulu ezinkambini ze-RF kanye ne-microwave, futhi kubalulekile ukuze kuqinisekiswe ukunemba kokuhlola nokulinganisa.
Qualwaveihlinzeka ngokunqanyulwa kwe-PIM ephansi kumafrikhwensi ukusuka ku-DC kuye ku-0.35GHz, futhi amandla afinyelela ku-200W. Ukunqanyulwa kwethu kwe-PIM ephansi kusetshenziswa kabanzi ezindaweni eziningi
