Iindaba - Umdibanisi weCavity 80-2700MHz: isisombululo sokudibanisa i-RF esineebhendi ezininzi esiphantsi, isisombululo esincinci sokudibanisa i-RF

Iumdibanisi wemingxunyaIqaliswe yi-Apex Microwave igubungela iibhendi ezimbini zonxibelelwano eziphambili ze-80-520MHz kunye ne-694-2700MHz, kwaye yenzelwe usetyenziso lokudibanisa imiqondiso ye-multi-band efana nonxibelelwano olungenazingcingo, iinkqubo zesikhululo sesiseko, kunye neenkqubo ze-antenna ezisasazwe yi-DAS. Ngokuzihlukanisa okuphezulu, ukulahleka okuphantsi kokufakwa kunye nokusebenza kakuhle kwe-intermodulation, le cavity combiner ibe lukhetho olufanelekileyo lokudibanisa inkqubo ye-RF esebenza kakhulu.

Iumdibanisi wemingxunyaisebenza kakuhle kuzo zombini iibhendi ze-P1 (80-520MHz) kunye ne-P2 (694-2700MHz), kunye nokulahleka kokufakwa kwe-P1 okuphantsi njenge≤Ukulahleka kokufakwa kwe-0.4dB kunye ne-P2≤0.6dB, nto leyo enciphisa ngempumelelo ukulahleka kwamandla enkqubo. Ukusebenza kwe-PIM kufikelela kwi--155dBc@900MHz kunye ne--161dBc@1900MHz, okuqinisekisa umgangatho wesiginali kwiindawo ezineenkampani ezininzi. Ilahleko yokubuya yi≥16.5dB, kwaye ukuhlukaniswa kwayo≥I-50dB kwibhendi ephambili yefrikhwensi, nto leyo ephucula kakhulu amandla okulwa nokuphazamiseka kwenkqubo.

Iumdibanisi wemingxunyaixhasa amandla aphakathi aphezulu angama-120W kunye namandla aphezulu afikelela kwi-3000W, afanelekileyo kwiimeko zonxibelelwano ezinamandla aphezulu.imvelisoujongano lusebenzisa isixhumi esiqhelekileyo se-4.3-10 sabasetyhini, ubungakanani obupheleleyo yi-187.2×130.4×31.8mm, ubunzima bayo buyi≤I-1.4kg, iqokobhe lenziwe nge-alloy ye-aluminium e-oxidized conductive, umphezulu ungakhethwa kwi-Gray, Akzo Nobel RA7035, i-Powder spraying, enenqanaba lokhuseleko lwe-IP67, efanelekileyo kwiindawo ezingqongqo zangaphandle nezemizi-mveliso.

Ukongeza,umdibanisi wemingxunyaiphumelele isiqinisekiso somgangatho wokukhuselwa kwendalo se-RoHS 6/6, uluhlu lobushushu bokusebenza luyi-35°C ukuya ku +65°C, kwaye ixhasa ukucutshungulwa kwembonakalo eyenzelwe abathengi kunye noqwalaselo lwe-interface, ihlangabezana neemfuno zeeprojekthi ezahlukeneyo ngokuguquguquka.

Njengesixhobo sokudibanisa i-RF esihlala sodwa nesizinzileyo, i-Apex Microwave's cavity combiner isetyenziswa kakhulu kwizikhululo zesiseko ze-5G, unxibelelwano lwezitimela, unxibelelwano olungxamisekileyo, iinkqubo zeradar, unxibelelwano lwenethiwekhi yabucala kunye nezinye iinkalo. Sisisombululo esikhethwayo kubathengi abafuna ukusebenza kakuhle kwenkqubo.
