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 10 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.
- Ngwa GaAs amplifier, nrụpụta ike okpukpu abụọ, nwere nnukwu uru na mgbagha dị ala.
- Single Chip Microcomputer (SCM) njikwa akụrụngwa na-arụ ọrụ, LCD na-egosiputa paramita, 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 yana ịnweta sistemụ njikwa netwọkụ.
- Mweghachi azụ nwere ike họrọ ọnọdụ mgbawa iji belata mkpọtụ mkpọtụ nke ọma wee belata nọmba nnata nke ihu.

Usoro teknụzụ nke akwụkwọ ntuziaka a dị ka usoro nha nke GY/T 194-2003 si dị
1. Na-aga n'ihu ngwa anya na-enweta akụkụ: na 10km ọkọlọtọ optical fiber, passive optical attenuator, na ọkọlọtọ transmitter nke ọkọlọtọ mejupụtara njikọ ule. Tọọ akara ngosi TV analog 59 PAL-D na oke 45/87MHz～550MHz n'okpuru mfu njikọ akọwapụtara. Nyefee mgbama mgbanwe dijitalụ n'ogo nke 550MHz ~ 862/1003MHz, ọkwa mgbama mgbanwe dijitalụ (na 8 MHz bandwit) dị 10dB dị ala karịa ọkwa ihe mgbaàmà analog. Mgbe ike ntinye anya nke onye na-anata anya bụ -2dBm, ọkwa mmepụta RF bụ 108dBμV, na 9dB mmepụta tilt, tụọ C/CTB, C/CSO, na C/N.
2. Akụkụ mbufe ngwa anya azụ: Njikọ flatness na NPR ike nso bụ njikọ indexes nke mejupụtara ihe na-ebugharị ngwa anya azụ na onye nnata ngwa anya azụ.
Rịba ama: Mgbe ọkwa mmepụta ọkwa bụ nhazi zuru oke nke usoro na ike anya na-enweta -2dBm, akụrụngwa na-ezute ọkwa mmepụta kachasị nke njikọ njikọ. Mgbe nhazi usoro ahụ na-ebelata (ya bụ, ọwa mgbasa ozi na-ebelata), ọkwa mmepụta nke akụrụngwa ga-abawanye.
Ọkwa Enyi na Enyi: Na-atụ aro ka ịtọọ akara ngosi RF ka ọ bụrụ 6 ~ 9dB tilt n'ime ngwa injinịa bara uru iji melite ndeksi na-adịghị adị (n'okpuru ọnụ) nke sistemụ eriri.
