Umgomo wokusebenza kanye nokuhlaziywa kokusetshenziswa kwe-coupler

I-Coupler iyisisetshenziswa esenziwayo esisetshenziselwa ukudlulisa amasignali phakathi kwamasekhethi ahlukene noma amasistimu. Isetshenziswa kabanzi kumafrikhwensi omsakazo nasezinkundleni ze-microwave. Umsebenzi wayo oyinhloko ukuhlanganisa ingxenye ethile yamandla asuka entanjeni yokudlulisela eyinhloko kuya kulayini wesibili ukuze kuzuzwe ukusatshalaliswa kwesignali, ukuqapha noma impendulo.

I-coupler isebenza kanjani

Izithandani ngokuvamile zihlanganisa izintambo zokudlulisela noma izakhiwo ze-waveguide, ezidlulisela ingxenye yamandla esignali kulayini oyinhloko embobeni yokuxhuma ngomthelela wokuhlanganisa wezinkambu zikazibuthe. Le nqubo yokuhlanganisa ngeke ithinte kakhulu ukudluliselwa kwesignali yomugqa oyinhloko, ukuqinisekisa ukusebenza okuvamile kwesistimu.

Izinhlobo eziyinhloko zama-couplers

I-Directional Coupler: Inezimbobo ezine futhi ingakwazi ukuhlanganisa ingxenye yesiginali yokufaka endaweni ethile yokuphuma yokuqapha isignali nokulawula impendulo.

Isihlukanisi Samandla: Sabalalisa amasiginali okokufaka ezimbobeni eziningi zokuphumayo ngezilinganiso ezilinganayo, ngokuvamile ezisetshenziswa ezinhlelweni zama-antenna kanye nezinhlelo zamashaneli amaningi.

I-Hybrid Coupler: Ingahlukanisa isignali yokufaka ibe amasiginali amaningi okukhipha ama-amplitude alinganayo kodwa izigaba ezihlukene. Isetshenziswa kabanzi kumashifters wesigaba kanye nama-amplifiers alinganiselayo.

Amapharamitha angukhiye we-coupler

I-Coupling Factor: Ibonisa isilinganiso samandla esignali atholwe imbobo yokuhlanganisa emandleni okufaka, ngokuvamile avezwa ngama-decibel (dB).

Ukuhlukaniswa: Ikala izinga lokuhlukaniswa kwesignali phakathi kwezimbobo ezingasetshenzisiwe. Lapho ukuhlukaniswa kuphezulu, kuncane ukuphazamiseka phakathi kwezimbobo.

Ukulahlekelwa Kokufaka: ibhekisela ekulahlekeni kwamandla lapho isignali idlula ku-coupler. Ukuncipha kokulahlekelwa kokufaka, kulapho izinga lokudluliswa kwesignali liphezulu khona.

Isilinganiso segagasi esimile (VSWR): sibonisa ukufaniswa kokuphazamiseka kwembobo ye-coupler. Uma i-VSWR isondela ku-1, kuba ngcono ukusebenza okufanayo.

Izindawo zokufaka izicelo zama-couplers

Ukuqapha amasignali: Kuzinhlelo zefrikhwensi yomsakazo, ama-couplers asetshenziselwa ukukhipha ingxenye yesiginali yokuqapha nokulinganisa ngaphandle kokuphazamisa ukudluliswa kwesignali eyinhloko.

Ukusatshalaliswa kwamandla: Kuhlelo lwe-antenna, ama-couplers asetshenziselwa ukusabalalisa amasiginali ngokulinganayo ezintweni zothiyela ngazinye ukuze kuzuzwe ukwakheka kwe-beamform nokulawula isiqondiso.

Ukulawulwa kwempendulo: Kumasekhethi we-amplifier, ama-couplers asetshenziselwa ukukhipha ingxenye yesiginali yokuphumayo futhi ayibuyisele kokokufakayo ukuze kuzinze inzuzo nokuthuthukisa ukuhambisana.

Ukuhlanganiswa kwesignali: Ezinhlelweni zokuxhumana, ama-couplers angasetshenziswa ukuze ahlanganise amasiginali amaningi abe isignali eyodwa ukuze adlulise futhi acutshungulwe kalula.

Inqubekelaphambili yezobuchwepheshe yakamuva

Ngokuthuthuka okusheshayo kobuchwepheshe bezokuxhumana, izidingo zokusebenza zama-couplers mayelana nemvamisa ephezulu, amandla aphezulu kanye nomkhawulokudonsa obanzi zikhula njalo. Eminyakeni yamuva, imikhiqizo ye-coupler esekelwe ezintweni ezintsha kanye nezinqubo ezintsha ziye zaqhubeka nokuvela, ngokulahlekelwa okuphansi kokufaka, ukuhlukaniswa okuphezulu kanye nebhendi ye-frequency yokusebenza ebanzi, ukuhlangabezana nezidingo zokuxhumana kwe-5G, izinhlelo ze-radar, ukuxhumana kwe-satellite kanye nezinye izinkambu.

Ekuphetheni

Njengengxenye ebalulekile ezinhlelweni ze-RF ne-microwave, ama-couplers adlala indima ebalulekile ekudluliseni isignali, ukusatshalaliswa kanye nokuqapha. Ukuqonda isimiso sayo sokusebenza, uhlobo, amapharamitha angukhiye nezindawo zohlelo lokusebenza kuzosiza ukukhetha i-coupler efanele futhi kuthuthukise ukusebenza kwesistimu kumaphrojekthi wangempela.
