Lipotolohong tsa RF le microwave, li-circulator le li-isolator ke lisebelisoa tse peli tsa bohlokoa tse sebelisoang haholo ka lebaka la mesebetsi ea tsona e ikhethang le lits'ebetso. Ho utloisisa litšoaneleho tsa bona, mesebetsi le maemo a ts'ebeliso ho tla thusa baenjiniere ho khetha tharollo e nepahetseng meralong ea 'nete, ka hona ho ntlafatsa ts'ebetso ea sistimi le ho ts'epahala.
1. Circulator: Motsamaisi oa tataiso oa matšoao
1. Potoloho ke eng?
A circulator ke sesebelisoa se sa tsitsang se atisang ho sebelisa lisebelisoa tsa ferrite le matla a khoheli a ka ntle ho finyella phetisetso ea unidirectional ea matšoao. Hangata e na le likou tse tharo, 'me matšoao a ka fetisoa feela pakeng tsa likou ka tsela e tsitsitseng. Mohlala, ho tloha koung ea 1 ho ea koung ea 2, ho tloha koung ea 2 ho ea koung ea 3, le ho tloha koung ea 3 ho khutlela koung ea 1.
2. Mesebetsi e ka sehloohong ea potoloho
Kabo ea mats'oao le ho kopanya: tsamaisa matšoao ho likoung tse fapaneng tsa tlhahiso ka tsela e tsitsitseng, kapa kopanya matshwao ho tloha likoung tse ngata ho ea koung e le 'ngoe.
Fetisetsa le ho amohela ho itšehla thajana: e sebelisoa joalo ka duplexer ho fihlela ho itšehla thajana ha phetisetso le ho amohela matšoao ka antenna e le 'ngoe.
3. Litšobotsi tsa li-circulator
Ho se lumellane: matšoao a ka fetisoa ka tsela e le 'ngoe feela, ho qoba tšitiso e khutlelang morao.
Tahlehelo e tlase ea ho kenya: tahlehelo ea matla a tlase nakong ea phetisetso ea matšoao, haholo-holo e loketseng lits'ebetso tse phahameng haholo.
Ts'ehetso ea Wideband: e ka koahela maqhubu a mangata ho tloha MHz ho ea GHz.
4. Litšebeliso tse tloaelehileng tsa li-circulator
Sistimi ea Radar: e arola mochini o fetisang molaetsa ho moamoheli ho thibela matšoao a phetisetso ea matla a phahameng ho senya sesebelisoa se amohelang.
Sistimi ea puisano: e sebelisetsoa ho tsamaisa mats'oao le ho fetola li-antenna tse ngata.
Sistimi ea Antenna: e ts'ehetsa ho itšehla thajana ha matšoao a fetisoang le a amoheloang ho ntlafatsa botsitso ba sistimi.
II. Isolator: mokoallo oa tšireletso ea lets'oao
1. Motho ea itšehlang thajana ke eng?
Li-Isolators ke mofuta o ikhethileng oa li-circulator, hangata li na le likou tse peli feela. Mosebetsi oa eona o ka sehloohong ke ho hatella ponts'o ea lets'oao le ho khutla, ho sireletsa lisebelisoa tse hlokolosi hore li se ke tsa sitisoa.
2. Mesebetsi e ka sehloohong ea batho ba itšehlang thajana
Ho itšehla thajana: thibela mats'oao a bonts'itsoeng hore a se ke a khutlela morao ho lisebelisoa tse ka pele (tse kang li-transmitters kapa amplifiers) ho qoba mocheso o feteletseng kapa ho senyeha ha ts'ebetso ea lisebelisoa.
Tšireletso ea tsamaiso: lipotolohong tse rarahaneng, li-isolator li ka thibela ho kena-kenana pakeng tsa li-module tse haufi le ho ntlafatsa botšepehi ba tsamaiso.
3. Litšobotsi tsa batho ba itšehlang thajana
Phetiso ea unidirectional: lets'oao le ka fetisoa feela ho tloha pheletsong ea tlhahiso ho isa pheletsong ea tlhahiso, 'me lets'oao le ka morao le hatelloa kapa le kenngoa.
Ho itšehla thajana ho phahameng: ho fana ka phello e phahameng haholo ea khatello ho matšoao a bonts'itsoeng, hangata ho fihla ho 20dB kapa ho feta.
Tahlehelo e tlase ea ho kenya: e tiisa hore tahlehelo ea matla nakong ea phetisetso ea matšoao a tloaelehileng e tlase kamoo ho ka khonehang.
4. Tšebeliso e tloaelehileng ea li-isolators
Tšireletso ea amplifier ea RF: thibela mats'oao a bonahatsoang hore a se ke a baka ts'ebetso e sa tsitsang kapa esita le tšenyo ea amplifier.
Sistimi ea puisano e se nang mohala: arola mojule oa RF ho sistimi ea antenna ea setsi.
Lisebelisoa tsa liteko: tlosa matšoao a bonts'itsoeng sesebelisoa sa ho lekanya ho ntlafatsa ho nepahala ha tlhahlobo.
III. Joang ho khetha sesebelisoa se nepahetseng?
Ha o rala lipotoloho tsa RF kapa microwave, khetho ea se potolohang kapa e itšehla thajana e lokela ho ipapisa le litlhoko tse ikhethileng tsa kopo:
Haeba o hloka ho aba kapa ho kopanya matšoao lipakeng tsa likou tse ngata, li-circulator lia khethoa.
Haeba sepheo sa mantlha ke ho sireletsa sesebelisoa kapa ho fokotsa tšitiso ho tsoa ho matšoao a bonts'itsoeng, li-isolator ke khetho e ntle.
Ho phaella moo, palo ea maqhubu, tahlehelo ea ho kenya, ho itšehla thajana le litlhoko tsa boholo ba sesebelisoa li tlameha ho nkoa ka botlalo ho netefatsa hore matšoao a ts'ebetso ea tsamaiso e itseng aa phethahala.
IV. Mekhoa ea Tsoelo-pele ea Bokamoso
Ka nts'etsopele ea theknoloji ea puisano e se nang mohala, tlhoko ea miniaturization le ts'ebetso e phahameng ea lisebelisoa tsa RF le microwave e ntse e eketseha. Li-circulator le li-isolator li ntse li tsoela pele butle-butle ka litsela tse latelang:
Tšehetso ea maqhubu a phahameng: tšehetso ea lihlopha tsa maqhubu a millimeter (joalo ka 5G le millimeter wave radar).
Moralo o kopaneng: o kopantsoe le lisebelisoa tse ling tsa RF (joalo ka li-filters le li-divider tsa motlakase) ho ntlafatsa ts'ebetso ea sistimi.
Theko e tlase le miniaturization: sebelisa lisebelisoa tse ncha le lits'ebetso tsa tlhahiso ho fokotsa litšenyehelo le ho ikamahanya le litlhoko tsa lisebelisoa tsa terminal.
