Akayunguruzo gato

Itondekanya rya gatatu Intermodulation cyangwa 3 rd Itondekanya IMD ni mugihe ibimenyetso bibiri muri sisitemu y'umurongo, kubera ibintu bidafite umurongo bikora ikimenyetso cya kabiri gihuza ikindi kimenyetso cyumuvuduko wibanze gitanga gukubita (kuvanga) byakozwe nibimenyetso simusiga.

Umuyobozi-mw Intangiriro kuri PIM muyunguruzi

RF hasi ya PIM ya bande ya filteri. Iyungurura-yambere yungururwa yashizweho kugirango itange imikorere isumba iyindi, kuyungurura ibimenyetso utifuzaga no kugabanya intermodulation ya gatatu (gahunda ya 3 IMD) muri sisitemu ya RF.

Iyo ibimenyetso bibiri muri sisitemu y'umurongo bikorana nibintu bidafite umurongo, intermodulation ya gatatu ibaho, bikavamo ibimenyetso simusiga. RF RF PIM Bandpass Filters yakozwe kugirango itange akayunguruzo keza kandi igabanye ingaruka zo kugoreka intermodulation, kugabanya iki kibazo neza.

Hamwe nubuhanga bwabo buhanitse hamwe nubuhanga bwuzuye, bande ya filteri itanga urwego rwo hejuru rwo guhitamo, kwemerera gusa ibimenyetso bya RF byifuzwa kunyura mugihe uhuza imirongo idakenewe. Ibi byemeza ko sisitemu ya RF ikora hamwe nuburyo bwiza kandi butabangamiye, kuzamura ubwiza bwibimenyetso nibikorwa rusange.

Waba ukora mubitumanaho, imiyoboro itagikoreshwa, cyangwa ikindi kintu icyo ari cyo cyose cya RF, RF yo hasi ya PIM ya bande ya filteri nigisubizo cyiza cyo kohereza ibimenyetso bisukuye, byizewe. Ubwubatsi bwarwo bukomeye hamwe nibikoresho byujuje ubuziranenge bituma bikwiranye n’ibidukikije byinshi ndetse n’ibikorwa.

Usibye ubushobozi bwabo bwo hejuru bwo kuyungurura, bande ya filteri ya bande yashizweho kugirango yinjizwe byoroshye muri sisitemu ya RF iriho, bituma iba igisubizo cyinshi kandi gifatika kubikorwa bitandukanye. Hamwe nimikorere yabo yizewe nubwubatsi burambye, urashobora kwizera RF yacu yo hasi ya PIM bandpass ya filteri kugirango itange ibisubizo bihamye mubisabwa RF ibidukikije.

Inararibonye itandukaniro RF yacu yo hasi ya PIM bandpass muyunguruzi irashobora kuzana sisitemu ya RF. Kuzamura kuri ubu buryo bushya bwo kuyungurura kandi ujyane imikorere ya RF kurwego rukurikira.
