Incazelo Yomkhiqizo
1. Isifinyezo Somkhiqizo
SA1300CI-amplifier ye-trunk yangaphandle eqondiswa kabili yochungechunge iyi-amplifier entsha ethuthukisiwe ye-high-gain. Umklamo wesekethe ovuthiwe nowenziwe kahle, inqubo yangaphakathi yesayensi nenengqondo kanye nezinto ezisezingeni eliphezulu, kuqinisekisa inzuzo ezinzile kanye nokuphambuka okuphansi. Kuyisinqumo esingcono kakhulu sokwakha inethiwekhi yokudlulisa ye-CATV enkulu noma ephakathi nendawo.
2. Izici Zokusebenza
- Isigaba esingaphambi kwendlela samukela imodyuli entsha ye-high index engenisiwe yomsindo ophansi we-push-pull amplifier noma imodyuli ye-GaAs push-pull, isigaba sokuphuma sisebenzisa i-high index entsha engenisiwe kabili yamandla.yimodyuli ye-amplifier noma imodyuli ye-amplifier ye-GaAs. Inkomba engeyona eqondile ilungile futhi izinga lokukhipha lizinzile kakhudlwana. Indlela yokubuya isebenzisa imodyuli ye-amplifier entsha engenisiwe enenkomba ephezulu. Ukuphambuka kuphansi futhi isilinganiso sesignali kuya kumsindo siphezulu.
- Kulula kakhulu ukulungisa amaphutha ngenxa yesihlungi se-duplex se-plug-in, i-equalizer kanye ne-attenuator ye-plug-in engaguquki (noma elungisekayo), kanye nama-port okuthola ulwazi ku-inthanethi angokwesayensi futhi anengqondo.
- Imishini ingasebenza isikhathi eside ngokuqhubekayo ngaphansi kwesimo sezulu esibi sangaphandle. Ngenxa yendlu engangeni manzi ye-aluminium, ugesi wokushintsha othembekile kakhulu kanye nohlelo oluqinile lokuvikela umbani.
- Igobolondo lisebenzisa umklamo we-modular ohlanganisiwe; ukulungiswa kwemishini, ukushintshwa, kanye nokulungisa amaphutha kulula.
3. Umhlahlandlela Woku-oda
Sicela uqinisekise: imvamisa yokuhlukanisa izixhumanisi eziya phezulu kanye nezixhumanisi eziya phansi zezindlela eziya ezinhlangothini ezimbili.
4. Amathiphu Akhethekile:
- Ngaphambi kokusebenzisa umkhiqizo kumele kube nokusikwa okuthembekile!
- Umthamo omkhulu womkhiqizo wokushisa ngokweqile ngu-10A.
