Imigaqo ephambili kunye nokusetyenziswa okutsha kwee-couplers ezikhokelayo

Izihlanganisi ezikhokelayoZizixhobo ezibalulekileyo ezingasebenziyo kwiinkqubo ze-RF kunye ne-microwave, kwaye zisetyenziswa kakhulu ekujongeni imiqondiso, ukusasazwa kwamandla kunye nokulinganisa. Uyilo lwazo olunobuchule lubenza bakwazi ukukhupha izinto zemiqondiso kwicala elithile ngaphandle kokuphazamisana nokudluliselwa kwesignali ephambili.

Imigaqo yoyiloizihlanganisi zesikhokelo

Izihlanganisi ezikhokelayozihlala zenziwe ngemigca emibini yokudlulisela okanye ii-waveguides, kwaye zifezekisa ukuhanjiswa kwamandla kwicala elithile ngesakhiwo esithile sokudibanisa. Uyilo oluqhelekileyo luquka ii-waveguides couplers ezineembobo ezimbini, ii-microstrip line couplers, njl. Eyona nto iphambili kukufezekisa ukwahlulahlula okusebenzayo kwamaza angaphambili nangasemva ngokulawula ngokuchanekileyo ubungakanani kunye nesithuba sesakhiwo sokudibanisa.

Ukusetyenziswa kweizihlanganisi zesikhokelo

Ukubeka iliso kunye nokulinganisa isignali: Kwiinkqubo ze-RF,izihlanganisi zesikhokelozisetyenziselwa ukutsala inxalenye yesignali yokubeka esweni nokulinganisa ngaphandle kokuchaphazela ukudluliselwa kwesignali ephambili. Oku kubalulekile ekulungiseni iimpazamo zenkqubo kunye novavanyo lokusebenza.

Ukusasazwa kwamandla kunye nokuhlanganiswa:Izihlanganisi ezikhokelayoinokusasaza isignali yokufaka kwiiports ezininzi zokukhupha, okanye idibanise isignali ezininzi zibe sisignali enye, kwaye isetyenziswa kakhulu kwii-antenna arrays nakwiinkqubo zonxibelelwano ezineetshaneli ezininzi.

Ukuzahlula kunye nokukhusela: Kwezinye izicelo,izihlanganisi zesikhokelozisetyenziselwa ukwahlukanisa iindawo ezahlukeneyo zesekethe, ukuthintela ukuphazamiseka kwesignali okanye ukugqithisa kakhulu, kunye nokukhusela ukusebenza okuqhelekileyo kwezixhobo ezinobuthathaka.

Inkqubela phambili yetekhnoloji yamva nje

Ngophuhliso olukhawulezileyo lwetekhnoloji yonxibelelwano, uyilo lweizihlanganisi zesikhokeloikwahlala ivelisa izinto ezintsha. Kwiminyaka yakutshanje,izihlanganisi zesikhokeloNgokusekelwe kwizixhobo ezintsha kunye netekhnoloji ye-micromachining ifikelele kwiibhendi ezibanzi zokusebenza, ilahleko eziphantsi zokufakelwa, kunye nokukwazi okuphezulu kokuphatha amandla. Ukongeza, umkhwa wokudibanisa kunye nokunciphisa amandla wenza kube lula ukuba ii-couplers ezikhokelayo zifakwe kwiinkqubo ze-elektroniki ezintsonkothileyo, ukuhlangabezana neemfuno zezixhobo zonxibelelwano zanamhlanje zokusebenza okuphezulu kunye noyilo oluncinci.

Isiphelo

Njengenxalenye ephambili kwiinkqubo zeRF kunye ne-microwave,izihlanganisi zesikhokelozibaluleke kakhulu kubuchwepheshe bonxibelelwano banamhlanje ngenxa yoyilo lwazo olunobuchule kunye nokusetyenziswa kwazo ngokubanzi. Ngokuqhubeka nokuqhubela phambili kobuchwepheshe, ii-couplers ezikhokelayo ziya kudlala indima ebaluleke ngakumbi kwiinkqubo eziphezulu ze-frequency, amandla aphezulu kunye neenkqubo ezintsonkothileyo.
