Cavity combiner 80-2700MHz: kwigunga cyane, gutakaza bike-bande RF ihuza igisubizo

Uwitekacavity combineryatangijwe na Apex Microwave ikubiyemo ibice bibiri byingenzi byitumanaho byitumanaho rya 80-520MHz na 694-2700MHz, kandi byateguwe kubice byinshi byerekana ibimenyetso byerekana ibimenyetso nkitumanaho ridafite insinga, sisitemu ya sitasiyo, na DAS ikwirakwiza antenne. Hamwe no kwigunga kwinshi, igihombo gito cyo kwinjiza hamwe nibikorwa byiza bya intermodulation, iyi cavite ikomatanya yahindutse uburyo bwiza bwo guhuza imikorere ya RF ikora neza.

Uwitekacavity combinerikora neza mumatsinda yombi ya P1 (80-520MHz) na P2 (694-2700MHz), hamwe nigihombo cya P1 cyo hasi nko≤0.4dB na P2 igihombo cyo kwinjiza≤0.6dB, kugabanya neza gutakaza ingufu za sisitemu. Imikorere ya PIM igera kuri -155dBc @ 900MHz na -161dBc @ 1900MHz, ikemeza ubwiza bwibimenyetso mubidukikije byinshi. Igihombo cyo kugaruka ni≥16.5dB, kandi kwigunga ni≥50dB mumurongo wingenzi wumurongo, utezimbere cyane ubushobozi bwo kurwanya-kwivanga kwa sisitemu.

Uwitekacavity combinerishyigikira ingufu ntarengwa zingana na 120W nimbaraga zo hejuru zingana na 3000W, zikwiranye nibihe byitumanaho rikomeye. UwitekaibicuruzwaImigaragarire ifata 4.3-10 ihuza igitsina gore, ubunini muri rusange ni 187.2×130.4×31.8mm, uburemere ni≤1.4kg, igikonoshwa gikozwe muri aluminiyumu ya aluminiyumu ikora neza, ubuso bushobora gutoranywa muri Gray, Akzo Nobel RA7035, gutera ifu, hamwe nurwego rwo kurinda IP67, bikwiranye no hanze y’inganda n’inganda.

Byongeyeho ,.cavity combineryatsinze impamyabumenyi ya RoHS 6/6 yo kurengera ibidukikije, igipimo cy'ubushyuhe ni -35°C kugeza kuri +65°C, kandi ishyigikira umukiriya yihariye kugaragara no gutunganya ibice, guhuza byoroshye ibikenewe byimishinga itandukanye.

Nkigikoresho cyo kwigunga cyane, gihamye cyane ya synthesis ya RF, imashini ya cavite ya Apex Microwave ikoreshwa cyane muri sitasiyo fatizo ya 5G, itumanaho rya gari ya moshi, itumanaho ryihutirwa, sisitemu ya radar, itumanaho ryigenga nizindi nzego. Nibisubizo byatoranijwe kubakiriya bakurikirana imikorere ya sisitemu nziza.
