1. Chidule cha mankhwala
Mtengo wa SA1300Cmndandanda wakunja wa bi-directional trunk amplifier ndiye amplifier watsopano wotukuka kwambiri. Okhwima ndi wokometsedwa dera kapangidwe, sayansi ndi wololera mkati ndondomeko ndi zipangizo apamwamba, kuonetsetsa kupindula khola ndi otsika kupotoza. Ndi chisankho chabwino kwambiri chomanga ma netiweki akulu kapena apakati a CATV bi-directional transmission network.
2. Makhalidwe Antchito
- Njira yakutsogolo itengera gawo laposachedwa kwambiri lomwe latulutsidwa kunja kwa phokoso lotsika-koka amplifier kapena gawo la GaAs push-pull module, gawo lotulutsa limatenga mphamvu zatsopano kwambiri zomwe zatumizidwa kunjaygawo la amplifier kapena gawo la GaAs amplifier. Mlozera wopanda mzere ndi wabwino ndipo mulingo wotuluka ndiwokhazikika. Njira yobwerera imatengera gawo laposachedwa kwambiri lomwe latumizidwa kunja kwa amplifier. Kusokoneza kumakhala kochepa ndipo chiŵerengero cha chizindikiro ku phokoso ndichokwera.
- Ndikosavuta kukonza chifukwa cha plug-in duplex fyuluta, plug-in fixed (kapena chosinthika) yofananira ndi chowongolera, komanso madoko asayansi komanso omveka ozindikira pa intaneti.
- Zida zimatha kugwira ntchito nthawi yayitali mosalekeza pansi pazikhalidwe zoyipa zakunja. Chifukwa cha aluminiyumu yopanda madzi nyumba, kudalirika kwakukulu kosinthira magetsi komanso chitetezo cholimba cha mphezi.
- Chipolopolocho chimatengera mawonekedwe ophatikizidwa; kukonza zida, kusintha, ndi kukonza zolakwika ndizosavuta.
3. Kalozera Woyitanitsa
Chonde tsimikizirani: uplink ndi downlink kugawanika pafupipafupi kwa njira ziwiri.
4. Malangizo Apadera:
- Musanagwiritse ntchito mankhwala ayenera kukhala odalirika maziko!
- Kuchuluka kopitilira muyeso kwa mankhwalawa ndi 10A.
