TS'ELISO HONA

Li-Attenuators tse tlase tsa PIM ke li-attenuators tsa RF le microwave tse etselitsoeng ka ho khetheha ho fokotsa phello ea passive intermodulation (PIM). Phello ea PIM e bua ka likarolo tse eketsehileng tsa maqhubu a hlahisoang ka lebaka la liphello tse sa tloaelehang likarolong tse sa sebetseng. Likarolo tsena li tla kena-kenana le letšoao la pele le ho fokotsa ts'ebetso ea tsamaiso.

Morero:

1. Tlhokomelo ea Letšoao: Lits'oants'o tse tlase tsa PIM li sebelisetsoa ho fokotsa ka nepo matla a mats'oao a RF le microwave ho sireletsa lisebelisoa tse amohelang hantle le maemo a mats'oao a taolo.
2. Fokotsa Phello ea Passive Intermodulation (PIM): Li-attenuators tse tlaase tsa PIM li fokotsa phello ea PIM ka ho sebelisa lisebelisoa tsa boleng bo phahameng le mekhoa e nepahetseng ea tlhahiso ho fokotsa liphello tse se nang moeli likarolong tse sa sebetseng.
3. Impedance e Bapisang: Motlakase oa PIM o tlaase o ka sebelisoa ho lumellana le ho senyeha ha tsamaiso, kahoo o fokotsa ho bonahatsa le maqhubu a emeng le ho ntlafatsa tshebetso ea tsamaiso.

Kopo:

1. Seteishene sa Motheo oa Puisano ea Mehala: Liteisheneng tsa motheo tsa puisano ea cellular, li-attenuators tse tlaase tsa PIM li sebelisoa ho fokotsa phello ea PIM, ka hona ho ntlafatsa ho hlaka ha matšoao le ho tšepahala ha khokahanyo ea puisano. Sena se bohlokoa haholo bakeng sa marang-rang a 4G le 5G.
2. Sistimi ea li-antenna: Lenaneong la li-antenna, attenuator e tlaase ea PIM e sebelisoa ho fokotsa phello ea PIM le ho ntlafatsa tshebetso le boleng ba pontšo ea antenna. Sena se thusa ho ntlafatsa lits'ebetso le litefiso tsa phetisetso ea data ea litsamaiso tsa puisano.
3. Tsamaiso ea Antenna e Ajoang (DAS): Litsamaisong tsa li-antenna tse ajoang, li-attenuators tse tlaase tsa PIM li sebelisoa ho fokotsa liphello tsa PIM, kahoo li ntlafatsa tshebetso ea tsamaiso le ho tšepahala. Sena se bohlokoa haholo bakeng sa litharollo tsa khaso ea waelese ea kahare le kantle.
4. Teko ea Microwave le RF: Lits'ebetsong tsa tlhahlobo ea microwave le RF, li-attenuators tse tlase tsa PIM li sebelisoa ho laola ka nepo matla a mats'oao le ho fokotsa litlamorao tsa PIM bakeng sa tlhahlobo e nepahetseng e phahameng le tekanyo.
5. Seea-le-moea le TV: Lits'ebetsong tsa seea-le-moea le TV, li-attenuators tse tlaase tsa PIM li sebelisoa ho fokotsa liphello tsa PIM le ho ntlafatsa boleng ba matšoao le ho fana ka tšireletso. Sena se thusa ho fana ka matshwao a hlakileng a mamelwang le a video.
6. Puisano ea Satellite: Litsamaisong tsa puisano tsa sathelaete, li-attenuators tse tlaase tsa PIM li sebelisoa ho fokotsa liphello tsa PIM le ho ntlafatsa ho tšepahala le boleng ba matšoao a li-link tsa puisano. Sena se bohlokoa haholo bakeng sa likhokahano tsa sathelaete tsa maqhubu a holimo.
Ka bokhuts'oane, li-attenuators tse tlase tsa li-intermodulation (Low PIM Attenuators) li sebelisoa haholo mafapheng a mangata joalo ka likhokahano tsa cellular, litsamaiso tsa li-antenna, litsamaiso tsa li-antenna tse ajoang, tlhahlobo ea microwave le RF, seea-le-moea le thelevishene le likhokahano tsa sathelaete. Ba ntlafatsa ts'ebetso ea sistimi le ho ts'epahala ka ho fokotsa litlamorao tsa PIM le ho laola matla a lets'oao ka nepo.

Qualwavee fana ka lintlha tse fapaneng tse nepahetseng tse phahameng le matla a phahameng a coaxial Low PIM Attenuators a koahela maqhubu a DC ~ 1GHz. Ka karolelano matla a ts'oaroang ke li-watts tse 150. Li-attenuators li sebelisoa lits'ebetsong tse ngata moo ho hlokahalang ho fokotsa matla.
