      Isifunda se-Baron

      I-Balun iyidivayisi yezimbobo ezintathu, noma isiguquli somugqa wokudlulisa i-broadband esixhuma amasekhethi kalayini wokudlulisela olinganiselayo nongalinganiseli ngokuguqula okokufaka okufanayo kube okokukhiphayo okuhlukile. Umsebenzi weBarron ukunika amandla uhlelo ukuthi lube ne-impedance ehlukile ...

      thuthukisa isifunda

      Kokubili i-buck circuit kanye ne-boost circuit yiziyingi ezibalulekile ekwakhiweni kwehadiwe, ikakhulukazi kuma-ONU ahlakaniphile namadivayisi we-OLT. Umsebenzi we-VOICE ekwakhiweni kwe-ONU usebenzisa i-boost circuit ukukhulisa amandla kagesi kanye nokuphakela amandla kumafoni angaphandle. Indlela engcono kakhulu...
