Sefe e ikhethileng ea RF Cavity 437.5MHz Band Pass Filter
Li-Filters tsa Cavity li bohlokoa haholo bakeng sa litlhoko tsa hau tsa puisano. Keenlion, feme ea rona e etelletseng pele, e sebetsa ka ho khetheha ho hlahiseng lisebelisoa tsa boleng bo holimo tsa puisano. Li-Filters tsa rona tsa Cavity li etselitsoe ho fana ka tahlehelo e tlase, khatello e phahameng, le matla a matla a matla, e leng se etsang hore e be tse loketseng indasteri ea puisano ea mehala le liteishene tsa mantlha. Li-Filters tsena tse ikhethileng tsa Cavity li etselitsoe ho ntlafatsa ts'ebetso ea lits'ebetso tsa hau tsa puisano, ho fihlela litlhoko le litlhoko tsa motho ka mong.
Kakaretso ea Sehlahisoa
Li-Filters tsa Cavity, karolo ea bohlokoa bakeng sa litlhoko tsa hau tsa puisano. Feme ea rona, Keenlion, ke mohlahisi ea ka sehloohong oa lisebelisoa tsa puisano tsa boleng bo holimo. Li-Filters tsa rona tsa Cavity li etselitsoe ho fana ka tahlehelo e fokolang, ho fokotseha ho phahameng, le matla a matla a matla, ho etsa hore e be sebaka se loketseng bakeng sa indasteri ea puisano ea mehala le liteishene tsa motheo.Li-Filters tsa rona tsa Cavity li etselitsoe ho ntlafatsa ts'ebetso ea mekhoa ea hau ea puisano. E le sehlahisoa se ka khonehang, se kopana le litlhoko le litlhoko tsa motho ka mong.
Lisebelisoa tse tloaelehileng
1.Sistimi ea puisano e se nang mohala - Filter ea Cavity e ka sebelisoa bakeng sa tokiso ea khafetsa le ho sefa lits'ebetsong tsa puisano tse se nang mohala, mme e ka hlokomela phetiso ea matšoao a ts'ebetso e phahameng.
Seteishene sa 2.Base - Filter ea Cavity e ka sebelisoa bakeng sa boemo ba matšoao le ho sefa ha setsi sa setsi ho ntlafatsa bokhoni ba ho lemoha matšoao a marang-rang a se nang mohala.
Puisano ea 3.Satellite - Filter ea Cavity e ka sebelisoa bakeng sa ho hloekisa lipontšo ka mekhoa ea puisano ea sathelaete ho ntlafatsa boleng ba matšoao le katleho ea phetisetso.
4.Aerospace - Filter ea Cavity e ka sebelisoa mekhoeng ea puisano ea lifofane le ho hloekisa lipontšo tsa radar sebakeng sa lifofane.
5. Lipuisano tsa Sesole - Sefate sa Cavity se ka sebelisoa bakeng sa boemo ba matšoao le ho sefa mekhoeng ea puisano ea sesole ho netefatsa phetisetso e nepahetseng ea matšoao le lekunutu.
