Izithombe Ezifakiwe Ze-RFTYT Eziphansi Ze-PIM Couplers Ezihlanganisiwe Noma Ezivulekile

Ama-RFTYT Ama-Couplers e-PIM aphansi ahlanganisiwe noma avulekile

I-coupler ye-intermodulation ephansi iyithuluzi elisetshenziswa kabanzi ezinhlelweni zokuxhumana ezingenantambo ukunciphisa ukuphazamiseka kwe-intermodulation kumadivayisi angenantambo. Ukuphazanyiswa kwe-intermodulation kubhekisela esimweni lapho izimpawu eziningi zidlula ohlelweni olungeyona i-linear ngesikhathi esisodwa, okuholela ekubonakaleni kwezingxenye zemvamisa ezingekho eziphazamisa ezinye izingxenye zemvamisa, okuholela ekunciphiseni ukusebenza kwesistimu engenantambo.

Ezinhlelweni zokuxhumana ezingenantambo, ama-couplers aphansi phakathi kwe-modulation avame ukusetshenziselwa ukuhlukanisa isignali yamandla aphezulu yokufaka kusuka kusignali yokukhipha ukuze kuncishiswe ukuphazamiseka phakathi kwe-modulation.

Ukubuka konke

Isixhumi esiphansi se-intermodulation sakhiwe kahle futhi singacindezela ngempumelelo ukuphazamiseka kwe-intermodulation, sithuthukise ukulingana kanye nobubanzi obuguqukayo besistimu. Singabela amasignali okufaka ngokulinganayo kumachweba amabili okukhipha, ngaleyo ndlela sinciphise ubuningi bamandla ezingxenyeni ezingezona eziqondile futhi sinciphise amathuba okushintshashintsha phakathi.

Ama-couplers aphakathi kwe-intermodulation aphansi angasebenza ebangeni elibanzi lemvamisa futhi afanele izinhlelo zokuxhumana ezingenantambo kuma-frequency band ahlukene. Angahlangabezana nezidingo zokuxhumana zama-frequency band ahlukene futhi agcine ukusebenza okuzinzile kwe-intermodulation.

Ama-couplers aphakathi kwe-modulation aphansi ngokuvamile asebenzisa izakhiwo ezifana nemigqa ye-microstrip kanye nama-waveguide e-coplanar, anobukhulu obuncane nesisindo. Lokhu kwenza kube lula ukuhlanganisa nokuhlela kumadivayisi angenantambo, konge isikhala, futhi kunikeze ukuguquguquka okungcono kwesistimu.

Ama-couplers aphakathi kwe-intermodulation aphansi angamelana namandla aphezulu okufaka ngaphandle kokubangela ukwehluleka kwesistimu noma ukuwohloka kokusebenza ngenxa yamandla aphezulu. Lokhu kubaluleke kakhulu ezinhlelweni zokuxhumana ezinamandla aphezulu, ezingaqinisekisa ukuthembeka nokuzinza kwesistimu.

Ama-couplers aphakathi kwe-intermodulation aphansi adlala indima ebalulekile ezinhlelweni zokuxhumana ezingenantambo, acindezela ngempumelelo ukuphazamiseka kwe-intermodulation futhi athuthukise ukusebenza kwesistimu. Ukusebenza kwayo okuhle kakhulu kwe-intermodulation, i-bandwidth ebanzi yemvamisa, ukuxhumanisa okulungisekayo, usayizi omncane, kanye nokubekezelelana kwamandla aphezulu kuyenza ibe yingxenye ebalulekile yokuklama nokwenza ngcono uhlelo lokuxhumana olungenantambo.
