Li-Attenuator tse tlase tsa PIM ke li-attenuator tsa RF le microwave tse etselitsoeng ka ho khetheha ho fokotsa phello ea passive intermodulation (PIM). Phello ea PIM e bolela likarolo tsa maqhubu a eketsehileng tse hlahisoang ka lebaka la litlamorao tse seng tsa mola likarolong tse sa sebetseng. Likarolo tsena li tla sitisa lets'oao la pele le ho fokotsa ts'ebetso ea sistimi.

Morero:

1. Ho Fokotsa Letšoao: Li-attenuator tse tlase tsa PIM li sebelisetsoa ho fokotsa matla a matšoao a RF le a microwave ka nepo ho sireletsa lisebelisoa tse amohelang le maemo a matšoao a taolo.
2. Fokotsa Phello ea ho Fetola Molumo (PIM): Li-attenuator tse tlase tsa PIM li fokotsa phello ea PIM ka ho sebelisa thepa ea boleng bo holimo le lits'ebetso tse nepahetseng tsa tlhahiso ho fokotsa litlamorao tse seng tsa mola likarolong tse sa sebetseng.
3. Ho Impedance e Amanang: Sethibela-matla sa PIM RF se tlase se ka sebediswa ho bapisa impedance ya sistimi, ka hona se fokotsa dipontsho le maqhubu a emeng le ho ntlafatsa tshebetso ya sistimi.

Kopo:

1. Setsi sa Motheo sa Puisano ea Liselefouno: Liteisheneng tsa motheo tsa puisano ea selefounu, li-attenuator tsa microwave tsa PIM tse tlase li sebelisoa ho fokotsa phello ea PIM, ka hona ho ntlafatsa ho hlaka ha lets'oao le ts'epahalo ea lihokelo tsa puisano. Sena se bohlokoa haholo bakeng sa marang-rang a 4G le 5G.
2. Sistimi ea Antenna: Sistimi ea antenna, sethibela-maqhubu sa PIM se tlaase sa millimeter se sebelisoa ho fokotsa phello ea PIM le ho ntlafatsa ts'ebetso le boleng ba lets'oao la antenna. Sena se thusa ho ntlafatsa sekhahla sa ho koahela le ho fetisetsa data ea litsamaiso tsa puisano.
3. Sistimi ea Antenna e Ajoang (DAS): Litsamaisong tsa antenna tse ajoang, li-attenuator tsa maqhubu a tlase a PIM mm li sebelisoa ho fokotsa litlamorao tsa PIM, ka hona ho ntlafatsa ts'ebetso ea sistimi le ts'epo. Sena se bohlokoa haholo bakeng sa litharollo tsa sekoahelo sa waelese kahare le kantle.
4. Teko ea microwave le RF: Litsamaisong tsa liteko tsa microwave le RF, li-attenuator tse tlase tsa PIM RF li sebelisoa ho laola matla a lets'oao ka nepo le ho fokotsa litlamorao tsa PIM bakeng sa liteko le tekanyo e nepahetseng haholo.
5. Radio le TV: Litsamaisong tsa radio le TV, li-attenuator tse tlase tsa PIM li sebelisoa ho fokotsa litlamorao tsa PIM le ho ntlafatsa boleng ba lets'oao le kabo. Sena se thusa ho fana ka matšoao a molumo le video a hlakileng haholoanyane.
6. Puisano ea Sathelaete: Litsamaisong tsa puisano ea sathelaete, li-attenuator tse tlase tsa PIM li sebelisoa ho fokotsa litlamorao tsa PIM le ho ntlafatsa ts'epo le boleng ba lets'oao la lihokelo tsa puisano. Sena se bohlokoa haholo bakeng sa puisano ea sathelaete ea maqhubu a phahameng.
Ka bokhutšoanyane, li-attenuator tse tlase tse sa sebetseng (Li-Attenuator tse tlase tsa PIM) li sebelisoa haholo mafapheng a mangata a kang puisano ea selefounu, litsamaiso tsa antenna, litsamaiso tsa antenna tse ajoang, tlhahlobo ea microwave le RF, radio le thelevishene, le puisano ea sathelaete. Li ntlafatsa ts'ebetso ea sistimi le ts'epo ka ho fokotsa litlamorao tsa PIM le ho laola matla a lets'oao ka nepo.

Qualwavee fana ka mefuta e fapaneng ya ho nepahala ho hoholo le coaxial e matla a hodimo. Li-Attenuator tse tlase tsa PIM di akaretsa maqhubu a DC~11GHz. Tshebetso e tloaelehileng ya matla e fihla ho di-watts tse 300. Li-attenuator di sebediswa dikopong tse ngata moo ho hlokahalang phokotso ya matla.
