Li-Couplers tse Tlase tsa PIM tse Tataisoang ka Tsela e le 'Ngoe RF BroadBand Microwave e Matla a Phahameng ea Coaial Millimeter Maqhubu a Radio a Leqhubu
Sehokelo sa Directional se Tlase sa PIM ke karolo e ikgethang ya RF e sa sebetseng e reretsweng ho latsoa matla a lets'oao a ho ya pele kapa a ho kgutlisa morao ha ka nako e ts'oanang e boloka bohloeki bo ikgethang ba lets'oao ka ho fokotsa ho sotha ha modumo o sa sebetseng (PIM). Dihokelo tsena di na le dibopeho tse nepahetseng tsa ho hokela tse bohlokwa bakeng sa ditsamaiso tsa sejwalejwale tse sebetsang hantle tsa waelese.
Likaroloana:
1. Botšepehi bo Ikhethang ba Pontšo
Moralo o tsoetseng pele o fokotsa ho sotha ha modumo o sa sebetseng (PIM). Tataiso e phahameng e netefatsa ho hokahana ha lets'oao ka nepo ka tšitiso e fokolang. Tshebetso e phahameng ya ho otloloha e boloka bohloeki ba lets'oao ho pholletsa le sebaka sa ts'ebetso.
2. Tshebetso ya Broadband
Khaso ea maqhubu a pharaletseng e tšehetsa lihlopha tse ngata tsa puisano. Tshebetso e tsitsitseng ho pholletsa le liphetoho tsa mocheso le maemo a tikoloho. Litšobotsi tse tsitsitseng tsa ho kopanya ho pholletsa le bandwidth ea ts'ebetso.
3. Kaho e Matla
Matlo a entsoeng ka mokhoa o nepahetseng a fana ka thepa e ntle ea tšireletso. Thepa e tšoarellang e mamella maemo a thata a ho kenya. Karolo e nyane ea sebopeho e nolofalletsa ho kopanngoa ha sistimi e tenyetsehang.
4. Ts'ebetso e Tšepahalang
Bokhoni bo botle ba ho sebetsana le matla bakeng sa ts'ebetso e tsoelang pele. Tahlehelo e tlase ea ho kenya e boloka ts'ebetso ea sistimi. Ts'ebetso e tsitsitseng ea VSWR e netefatsa boleng bo tsitsitseng ba lets'oao.
Likopo:
1. Mekhoa ea Puisano e se nang mohala
Marangrang a phepelo ea antenna seteisheneng sa motheo bakeng sa meralo ea motheo ea 5G/LTE. Litsamaiso tsa amplifier e kentsoeng ka tora (TMA). Litsamaiso tsa antenna tse ajoang (DAS) bakeng sa tšireletso ea kahare.
2. Teko le Tekanyo
Tlhokomelo ea matšoao litsamaisong tsa liteko tsa RF. Khokahano ea litšupiso bakeng sa teko ea intermodulation. Netefatso ea ts'ebetso ea sistimi le ho rarolla mathata.
3. Lifofane le Tšireletso
Litsamaiso tsa puisano tsa sathelaete. Lisebelisoa tsa radar le tsa ntoa ea elektroniki. Lihokelo tsa puisano tsa bohlokoa ka sepheo.
4. Kgaso le Radio ya Setsebi
Mekhoa ea ho kopanya li-transmitter. Tlhokomelo ea mohala oa phetiso ea phatlalatso. Marang-rang a kabo ea RF a matla a phahameng.
5. Melemo ea Tekheniki
E ntlafalitsoe bakeng sa ts'ebetso e tlase ea PIM lits'ebetsong tse hlokang boiteko bo bongata. Likhetho tse feto-fetohang tsa ho iketsetsa lia fumaneha. E entsoe ka likarolo tse nepahetseng bakeng sa ts'ebetso e tšepahalang. Teko e felletseng ea boleng e netefatsa ts'ebetso e tsitsitseng.
Qualwavee fana ka di-couple tsa broadband tse nang le PIM e tlase ka tsela e le nngwe tse fapaneng ho tloha ho 0.555GHz ho isa ho 2.7GHz. Di-couple di sebediswa haholo dikopong tse ngata.
