SR812ST-R bụ ihe nnata ngwa anya netwọkụ CATV kacha ọhụrụ. Igwe a na-ebu ụzọ na-anabata GaAs MMIC zuru oke, ampilifaya na-anabata modul GaAs. Nhazi sekit kachasị mma yana afọ 15 nke ahụmịhe imewe ọkachamara, na-eme ka akụrụngwa nweta ndeksi arụmọrụ dị mma. Njikwa microprocessor, ngosipụta dijitalụ nke paramita, nbibi injinịa dị mfe karị. Ọ bụ ngwá ọrụ bụ isi iji wuo netwọk CATV.
Njirimara arụmọrụ
- Nzaghachi dị elu PIN fotoelectric tube ntụgharị.
- Nhazi sekit kachasị mma, mmepụta usoro SMT, na ụzọ mgbama kachasị mma na-eme ka mgbasa ozi fotoelectric dịkwuo mma.
- mgbawa attenuation RF pụrụ iche, yana ezigbo RF attenuation na nha nha nha, izi ezi dị elu.
- GaAs amplifier ngwaọrụ, ike doubler mmepụta, nwere nnukwu uru na obere mgbagha.
- Single Chip Microcomputer (SCM) njikwa akụrụngwa na-arụ ọrụ, LCD gosipụtara paramita ahụ, ịdị mma na arụmọrụ nwere ọgụgụ isi yana arụmọrụ kwụsiri ike.
- Ọmarịcha arụmọrụ AGC, mgbe oke ike ntinye anya bụ -9 ~ 2dBm, ọkwa mmepụta anaghị agbanwe agbanwe, yana CTB na CSO agbanwebeghị.
- interface nkwukọrịta data echekwara, nwere ike jikọọ na klas Ⅱ onye na-aza njikwa netwọkụ, wee nweta sistemụ njikwa netwọkụ.
- Mweghachi azụ nwere ike họrọ ọnọdụ mgbawa iji belata mkpọtụ mkpọtụ nke ọma wee belata nọmba nnata nke ihu.
