Umfanekiso obonisiweyo weRFTYT Low PIM Couplers Combined or Open Circuit

Ii-RFTYT Low PIM Couplers eziDibeneyo okanye eziVulekileyo

I-low intermodulation coupler sisixhobo esisetyenziswa kakhulu kwiinkqubo zonxibelelwano ezingenazingcingo ukunciphisa ukuphazamiseka kwe-intermodulation kwizixhobo ezingenazingcingo. Ukuphazamiseka kwe-Intermodulation kubhekisa kwinto apho imiqondiso emininzi idlula kwinkqubo engeyomgca ngaxeshanye, nto leyo ebangela ukubonakala kwezixhobo ze-frequency ezingekhoyo eziphazamisana nezinye izixhobo ze-frequency, nto leyo ekhokelela ekunciphiseni ukusebenza kwenkqubo engenazingcingo.

Kwiinkqubo zonxibelelwano ezingenazingcingo, ii-couplers eziphantsi ze-intermodulation zihlala zisetyenziselwa ukwahlula isignali yamandla aphezulu engeniso kwisignali yokuphuma ukuze kuncitshiswe ukuphazamiseka kwe-intermodulation.

Isishwankathelo

Isihlanganisi esiphantsi se-intermodulation senziwe kakuhle kwaye sinokucinezela ngempumelelo ukuphazamiseka kwe-intermodulation, siphucule ulungelelwaniso kunye nobubanzi obuguqukayo benkqubo. Sinokwabela ngokulinganayo imiqondiso yokufaka kwiiports ezimbini zokukhupha, ngaloo ndlela sinciphisa uxinano lwamandla kwiinxalenye ezingezizo ezithe ngqo kwaye sinciphise amathuba okusebenzisa i-intermodulation.

Ii-couplers ezisebenzisa i-intermodulation ephantsi zinokusebenza kuluhlu olubanzi lwee-frequency kwaye zifanelekile kwiinkqubo zonxibelelwano ezingenazingcingo kwii-frequency bands ezahlukeneyo. Zingahlangabezana neemfuno zonxibelelwano zee-frequency bands ezahlukeneyo kwaye zigcine ukusebenza okuzinzileyo kwe-intermodulation.

Ii-couplers eziphantsi phakathi kwe-modulation zihlala zisebenzisa izakhiwo ezifana nemigca ye-microstrip kunye ne-coplanar waveguides, ezinobukhulu obuncinci kunye nobunzima. Oku kwenza kube lula ukudibanisa kunye nokubeka kwizixhobo ezingenazingcingo, okonga indawo, kunye nokubonelela ngokuguquguquka okungcono kwenkqubo.

Ii-couplers eziphantsi ze-intermodulation zinokumelana namandla aphezulu okufaka ngaphandle kokubangela ukusilela kwenkqubo okanye ukwehla kokusebenza ngenxa yamandla aphezulu. Oku kubaluleke kakhulu kwiinkqubo zonxibelelwano ezinamandla aphezulu, ezinokuqinisekisa ukuthembeka nokuzinza kwenkqubo.

Ii-couplers eziphantsi ze-intermodulation zidlala indima ebalulekileyo kwiinkqubo zonxibelelwano ezingenazingcingo, zithintela ngempumelelo ukuphazamiseka kwe-intermodulation kunye nokuphucula ukusebenza kwenkqubo. Ukusebenza kwayo okuhle kwe-intermodulation, i-bandwidth ebanzi ye-frequency, i-container ehlengahlengiswayo, ubungakanani obuncinci, kunye nokunyamezelana kwamandla aphezulu kuyenza ibe yinxalenye ebalulekileyo yoyilo kunye nokwenza ngcono inkqubo yonxibelelwano engenazingcingo.
