Molao-motheo le Ts'ebeliso ea Sekepe sa Likepe tse 3 Sistemeng ea Microwave

Kou ea 3Selika-likoeke sesebelisoa sa bohlokoa sa microwave/RF, se sebelisoang haholo ho tsamaiseng matshwao, ho arohanya le maemo a duplex. Sengoloa sena se hlahisa ka bokhutšoanyane molao-motheo oa sona oa sebopeho, litšobotsi tsa ts'ebetso le lits'ebetso tse tloaelehileng.

Kou e nang le li-port tse 3 ke eng?sejana sa potoloho?

Kou e 3sejana sa potolohoke sesebelisoa sa likou tse tharo se sa sebetseng, se sa buisaneng, 'me lets'oao le ka potoloha feela lipakeng tsa likou ka tsela e tsitsitseng:

Ho kenya ho tsoa koung ea 1 → tlhahiso ho tsoa koung ea 2 feela;

Ho kenya ho tsoa koung ea 2 → tlhahiso ho tsoa koung ea 3 feela;

Ho kenya ho tsoa koung ea 3 → tlhahiso ho tsoa koung ea 1 feela.

Ka mokhoa o loketseng, phetiso ea lets'oao la li-port tse 3sejana sa potolohoe latela tataiso e tsitsitseng: koung ea 1 → koung ea 2, koung ea 2 → koung ea 3, koung ea 3 → koung ea 1, e etsang tsela ea loop e le 'ngoe. Koung ka 'ngoe e fetisetsa matšoao feela koung e latelang, 'me letšoao le ke ke la fetisetsoa ka morao kapa la lutla likoung tse ling. Tšobotsi ena e bitsoa "ho se lumellane". Boitšoaro bona bo botle ba phetisetso bo ka hlalosoa ka matrix e tloaelehileng ea ho hasanya, e bontšang hore e na le tahlehelo e tlase ea ho kenya, ho itšehla thajana ho hoholo, le ts'ebetso ea phetisetso e lebang.

Likopo tse Tloaelehileng

Tšebeliso ea Sehatsetsi: E sebelisoa hangata lits'ebetsong tsa microwave tse matla haholo ho sireletsa li-transmitter tšenyo ea maqhubu a bonaletsang. Kou ea boraro e hokahantsoe le mojaro o lumellanang ho fihlela karohano e phahameng.

Mosebetsi oa Duplexer: Litsamaisong tsa radar kapa tsa puisano, e sebelisoa bakeng sa li-transmitter le li-receiver ho arolelana antenna e le 'ngoe ntle le ho sitisana.

Sistimi ea Amplifier ea ho Reflection: Ha e kopantsoe le lisebelisoa tse hanyetsang tse mpe (joalo ka li-diode tsa Gunn), li-circulator li ka sebelisoa ho arola litsela tsa ho kenya le ho ntša.
