Isixhumi se-RF 10dB se-LDC-0.4/6-10S samandla esignali

Isixhumi Esiqondisayo se-RF 10dB Samandla Esiginali
**Isici Sokuxhumanisa**: Igama elithi "10 dB" libhekisela kusici sokuxhumanisa, okusho ukuthi amandla asechwebeni elihlanganisiwe (okukhiphayo) angaphansi ngama-decibel ayi-10 kunamandla asechwebeni lokufaka. Ngokuphathelene nesilinganiso samandla, lokhu kuhambelana cishe nengxenye eyodwa kweziyishumi yamandla okufaka aqondiswa echwebeni elihlanganisiwe. Isibonelo, uma isignali yokufaka inezinga lamandla elingu-1 watt, okukhiphayo okuhlanganisiwe kuzoba cishe yi-0.1 watt.

**Ukuqondiswa**: I-coupler eqondisa indlela yenzelwe ukuthi ixhumanise amandla kusukela ohlangothini olulodwa (ngokuvamile ukuya phambili). Lokhu kusho ukuthi inciphisa inani lamandla ahlanganiswe kusukela ohlangothini oluphambene, okwenza ifaneleke ukusetshenziswa lapho ukuqondiswa kokugeleza kwesignali kubalulekile.

**Ukulahlekelwa Kokufakwa**: Nakuba inhloso eyinhloko yesixhumi sokuxhuma iwukukhipha amandla, kusekhona ukulahleka okuthile okuhlobene nokuba khona kwaso endleleni yesignali eyinhloko. Isixhumi sokuxhuma esisezingeni eliphansi noma esiklanywe kabi singase singenise ukulahleka okukhulu kokufakwa, kwehlisa ukusebenza kohlelo lonke. Kodwa-ke, izixhumi zokuxhuma eziklanywe kahle njengohlobo lwe-10 dB zivame ukuba nomthelela omncane esignalini eyinhloko, ngokuvamile zingaphansi kuka-0.5 dB kokulahlekelwa okwengeziwe.

**Ibanga Lemvamisa**: Ibanga lemvamisa yokusebenza kwe-coupler libalulekile njengoba linquma ububanzi bemvamisa engasebenza ngayo ngempumelelo ngaphandle kokwehla okukhulu kokusebenza. Ama-coupler asezingeni eliphezulu aklanyelwe ukusebenza ngaphakathi kwamabhendi athile emvamisa, ukuqinisekisa izici zokuxhuma ezihambisanayo kuyo yonke indawo.

**Ukuhlukaniswa**: Ukuhlukaniswa kubhekisela ekutheni i-coupler ihlukanisa kahle kangakanani izimpawu zokufaka nezokukhipha ukuze kuvinjelwe ukusebenzisana okungafuneki. Ukuhlukaniswa okuhle kuqinisekisa ukuthi ukuba khona komthwalo echwebeni elihlanganisiwe akuthinti isignali endleleni enkulu.
