Sefithara sa ho Emisa Sehlopha sa RF

Seteishene sa ho emisa leqhubu la RF FilterLeader Microwave Tech., boqapi ba morao-rao theknolojing ea ts'ebetso ea matšoao - Seteishene sa ho emisa leqhubu (BSF). Seteishene sena sa morao-rao se etselitsoe ho fokotsa likarolo tse itseng tsa maqhubu ka katleho ha ka nako e ts'oanang se lumella lets'oao le setseng ho feta ka tšitiso e nyane.

Li-filter tsa ho emisa maqhubu, tse tsejoang hape e le li-filter tsa ho emisa maqhubu, ke lisebelisoa tsa bohlokoa li-elektroniki le likhokahanong tsa mohala. Bokhoni ba eona ba ho thibela maqhubu a sa batleheng ka har'a sebaka se boletsoeng bo e etsa karolo ea bohlokoa lits'ebetsong tse kang ts'ebetso ea molumo, phokotso ea tšitiso ea maqhubu a seea-le-moea, le tlhahlobo ea matšoao a bongaka.

Li-filter tsa rona tsa bandstop li fana ka ho nepahala le ts'ebetso e sa bapisoeng, ho netefatsa hore ke likarolo tsa maqhubu feela tse khahlisang tse hatelloang ha ho ntse ho bolokoa botšepehi ba lets'oao ka kakaretso. Boemo bona ba ho nepahala bo bohlokoa maemong ao boteng ba maqhubu a itseng bo senyang boleng ba lets'oao kapa bo sitisang tlhahiso e lakatsehang.

E 'ngoe ea melemo e meholo ea lifilthara tsa rona tsa ho emisa band ke ho tenyetseha ha tsona. E ka kopanngoa ka mokhoa o se nang mathata lits'ebetsong le lisebelisoa tse fapaneng, ho kenyeletsoa lisebelisoa tsa molumo, marang-rang a puisano le lisebelisoa tsa bongaka. Hore na u sebetsa tlhahisong ea molumo, puisanong ea waelese kapa tlhokomelong ea 'mele, lifilthara tsa rona tsa ho emisa band li fana ka tharollo e tšepahalang bakeng sa ho laola likarolo tse sa batleheng tsa maqhubu.

Ho phaella moo, difilthara tsa rona tsa bandstop di entswe ka boqapi ho fana ka tshebetso e tsitsitseng le e tshepahalang, ho netefatsa botsitso le ho tshwarella ha nako e telele. Moralo wa yona o tiileng le dikarolo tsa boleng bo hodimo di etsa hore e lokele ditshebediso tse hlokang boiteko tsa indasteri hammoho le merero ya R&D.

Ka bokhutšoanyane, lifilthara tsa rona tsa bandstop li emela tsoelo-pele theknolojing ea ts'ebetso ea matšoao, li fana ka phokotso e nepahetseng le e sebetsang ea likarolo tse itseng tsa maqhubu. Ka ho tenyetseha ha eona le ho tšepahala ha eona, e loketse litsebi le bafuputsi ba batlang litharollo tse sebetsang hantle bakeng sa ho laola tšitiso ea maqhubu. Latsoa phapang ea lifilthara tsa rona tsa bandstop 'me u notlolle bokhoni bo felletseng ba lits'ebetso tsa hau tsa ts'ebetso ea matšoao.
