Incazelo Yomkhiqizo
1. Isifinyezo somkhiqizo
SA1300Cuchungechunge lwangaphandle lwe-bi-directional trunk amplifier iyisikhulisamazwi esisha esithuthukisiwe senzuzo ephezulu. Idizayini yesekethe evuthiwe nelungiselelwe, inqubo yangaphakathi yesayensi nenengqondo nezinto ezisetshenziswayo zekhwalithi ephezulu, iqinisekisa ukuzuza okuzinzile nokuhlanekezela okuphansi. Kuyisinqumo esingcono kakhulu sokwakha inethiwekhi yokudlulisa i-CATV enkulu noma emaphakathi.
2. Izici Zokusebenza
- Indlela eya phambili isigaba esandulelayo ithatha inkomba entsha kakhulu engenisiwe ephansi yomsindo we-push-pull amplifier module noma imojula ye-Push-pull ye-GaAs, isigaba sokukhiphayo sithatha amandla aphindwe kabili avela kwamanye amazwe anenkomba ephezulu kakhulu.yImojula ye-amplifier noma imojuli ye-GaAs amplifier. Inkomba engaqondile yinhle futhi izinga lokuphumayo lizinze kakhulu. Indlela yokubuya isebenzisa imojula ye-amplifier entsha kakhulu enenkomba ephezulu engenisiwe. Ukuhlanekezela kuphansi futhi isilinganiso sesignali kumsindo siphezulu.
- Kulula kakhulu ukulungisa iphutha ngenxa yesihlungi se-duplex se-plug-in, isilinganisi se-plug-in esigxilile (noma esilungisekayo) nesibambisi, kanye nezimbobo zokutholwa zesayensi nezinengqondo.
- Imishini ingakwazi ukusebenza isikhathi eside ngokuqhubekayo kancane kancane ngaphansi kwesimo esibi semvelo sangaphandle. Ngenxa yezindlu ze-aluminium ezingangeni manzi, ukuthembeka okuphezulu kokushintshwa kwamandla kanye nohlelo oluqinile lokuvikela umbani.
- Igobolondo lamukela umklamo oshumekiwe we-modular; ukunakekelwa kwemishini, ukushintshwa, kanye nokulungisa iphutha kulula.
3. Umhlahlandlela Woku-oda
Sicela uqinisekise: imvamisa yokuhlukanisa i-uplink ne-downlink yezindlela ezi-bi-directional.
4. Amathiphu Akhethekile:
- Ngaphambi kokusebenzisa umkhiqizo kumele kube nesisekelo esithembekile!
- Umthamo omkhulu we-overcurrent womkhiqizo ngu-10A.
