Molao-motheo le Tšebeliso ea 3-Port Circulator ho Microwave System

3-Boema-kepeSedikadikweke sesebelisoa sa bohlokoa sa microwave/RF, se sebelisoang hangata ho tsamaisa mats'oao, ho itšehla thajana le maemong a mabeli. Sengoliloeng sena se hlahisa ka bokhutšoanyane molao-motheo oa sebopeho, litšobotsi tsa ts'ebetso le lits'ebetso tse tloaelehileng.

3-port ke engselikalikoe?

Boema-kepe ba 3selikalikoeke sesebelisoa sa likou tse tharo se sa fetoheng, 'me lets'oao le ka potoloha lipakeng tsa likou ka tsela e tsitsitseng:

Kena ho tsoa boema-kepe ba 1 → tlhahiso feela ho tsoa ho boema-kepe ba 2;

Kenyo e tsoang boema-kepe ba 2 → tlhahiso feela ho tsoa ho boema-kepe ba 3;

Kena ho tsoa ho port 3 → tlhahiso feela ho tsoa ho port 1.

Ka mokhoa o loketseng, phetiso ea lets'oao la boema-kepe ba 3selikalikoee latela tsela e tsitsitseng: boema-kepe ba 1 → boema-kepe ba 2, boema-kepe ba 2 → boema-kepe ba 3, boema-kepe ba 3 → boema-kepe ba 1, bo etsang tsela e sa lekanyetsoang ea lupu. Boema-kepe bo bong le bo bong bo fetisetsa mats'oao boema-kepeng bo latelang feela, 'me lets'oao le ke ke la fetisetsoa ka morao kapa ho lutla likoung tse ling. Tšobotsi ena e bitsoa "no-reciprocity". Boitšoaro bona bo botle ba phetisetso bo ka hlalosoa ka mokhoa o tloaelehileng oa ho hasanya, o bontšang hore o na le tahlehelo e tlaase ea ho kenngoa, ho itšehla thajana ho phahameng, le ts'ebetso ea phetisetso ea tataiso.

Lisebelisoa tse Tloaelehileng

Tšebeliso ea Isolator: E sebelisoa hangata lits'ebetsong tsa microwave tse matla haholo ho sireletsa li-transmitter hore li se ke tsa senyeha. Boema-kepe ba boraro bo hokahane le mojaro o ts'oanang ho fihlela ho itšehla thajana ho phahameng.

Mosebetsi oa Duplexer: Lits'ebetsong tsa radar kapa tsa puisano, e sebelisoa bakeng sa li-transmitters le ba amohelang ho arolelana antenna e le 'ngoe ntle le ho kena-kenana.

Sistimi ea Amplifier ea Reflection: E kopantsoe le lisebelisoa tse mpe tsa ho hanyetsa (joalo ka Gunn diode), li-circulator li ka sebelisoa ho arola litsela tsa ho kenya le ho tsoa.
