Sharaxaada Alaabta

1. Soo koobida alaabta

SR812S waa qaabilaadaha indhaha ee shabakada CATV ee caalamiga ah oo leh transponder maamulka shabakada. Kahor-amp-ku wuxuu qaataa dhammaan-GaAs MMIC oo kor u qaadaya iyo ka-dambaysta-amp-ku wuxuu qaataa qalabka laba-weyn ee awoodda GaAs. Naqshad wareeg ah oo la wanaajiyey, oo ay weheliso khibradaha naqshadaynta RF ee sannadaheenna, qalabku wuxuu gaadhay tusmada waxqabadka sare. Waa moodal ku habboon shabakadda CATV.

2. Muuqaal

- jawaabta sare ee tuubada beddelka sawir-qaadista ee PIN, naqshadeynta bandwidth 1G.
- Attenuation iyo isleeggu waxay noqon karaan nooca buro si joogto ah loo hagaajin karoama geli nooca.(Ikhtiyaar)
- Wax soo saarka labajibbaaran ee awoodda, faa'iidada sare iyo qallooca hooseeya.
- Xakamaynta AGC ee indhaha, marka soo galinta kala duwanaanta awooda indhaha waa -7 ~ 2dBm, heerka wax soo saarka asal ahaan isma beddelin.
- Transponder network optional, taageero nidaamka maamulka network NMS.
