Kwiindawo zovavanyo lwelabhoratri kunye nokulinganisa apho imithwalo ye-coaxial ifumana ukusetyenziswa okukhawulezileyo ngexesha lokuchazwa kwe-antenna, ukuqinisekiswa kokusebenza kwe-transmitter, okanye ukulinganiswa kwe-impedance yesixhobo, ukupholisa umoya we-convection yendalo kudla ngokubonelela ngesisombululo esingabizi nesithembekileyo samanqanaba ombane angaphantsi kwama-watts angama-25. Ukusebenza okuthuleyo, iimfuno zokugcinwa ezingezizo, kunye nokususwa kwezinto ezihambayo kwenza imithwalo ye-coaxial epholileyo ngokwendalo ifaneleke kwizicelo zebhentshi apho icandelo linokuhlala lingasebenzi ixesha elide phakathi kweeseshoni zokulinganisa. Ukufakelwa kwezikhululo zesiseko kunye nezicelo zeziseko zonxibelelwano zihlala zisebenzisa imithwalo ye-coaxial kumanqanaba ombane aqhubekayo aphakathi kuluhlu lwama-watts angama-25 ukuya kwi-100, apho ukupholisa komoya okunyanzelekileyo okanye ukupholisa kwe-convection okwenziwe ngcono kubonelela ngokusebenza okufunekayo kobushushu ngelixa kusetyenziswa iinkqubo zomoya ezikhoyo ze-rack. Uyilo oluqinileyo noluhlala ixesha elide lwemithwalo ye-coaxial ye-Advanced Microwave ivumela ukuhlanganiswa okulula kwiindawo ezivaliweyo ze-rack ezisemgangathweni ze-19-intshi ngononophelo olufanelekileyo kwiindlela zokuhamba komoya kunye nokususwa kobushushu. Izicelo zokhuselo kunye neenqwelo moya, ngakumbi ezo zibandakanya iinkqubo zeradar ezinamandla aphezulu, izixhobo zemfazwe ze-elektroniki, okanye izikhululo zomhlaba zonxibelelwano lwesathelayithi, zihlala zifuna imithwalo ye-coaxial ekwaziyo ukusebenza ngokuqhubekayo kwi-100 ukuya kwi-500 watts, nto leyo edinga izisombululo zokupholisa ulwelo. Uluhlu lobushushu bokusebenza oluqala kwi -55°C ukuya kwi +125°C oluchaziweyo kwi-Advanced Microwave coaxial loads luqinisekisa ukusebenza okuthembekileyo kwiimeko ezimandundu zendalo ezidibana nazo kwizithuthi zomkhosi, kwiinqwelomoya, nakwiindawo ezikude. Ii-aplikeshini zokusasaza zifuna ukusebenza okuzinzileyo kwiinkqubo zothumelo olunamandla aphezulu, apho i-coaxial loads epholisiweyo lulwelo inika uzinzo lobushushu oluyimfuneko ekunciphiseni ukulahleka kwesignali kunye nokugcina umgangatho wokuphuma. Ukugubungela i-frequency ebanzi kunye neempawu ze-VSWR eziphantsi zihlala zizinzile kuyo yonke i-thermal cycling ekhoyo kwezi zicelo zinzima zomsebenzi oqhubekayo.

• Ukuhlanganiswa nochungechunge lwe-Advanced Microwave's CL

Imithwalo ye-coaxial ye-Advanced Microwave Technologies' series CL yenzelwe ukulungelelanisa zonke iindlela ezintathu eziphambili zokupholisa ngokusebenzisa uyilo olucwangcisiweyo loomatshini nobushushu olubonelela ngokuguquguquka kwiimfuno ezahlukeneyo zesicelo. Indlu enobuchule obuchanekileyo isebenza njengesisasazi sobushushu esisebenzayo sokupholisa ngokwendalo nangokunyanzeliswa kwe-convection ngelixa ibandakanya iindawo zokufakelwa ezithe tyaba kunye neendawo zokuncamathisela ezinemisonto ezenza kube lula ukuhlanganiswa nezinki zobushushu zangaphandle okanye ii-interfaces zokupholisa eziqhubayo. Kubathengi abafuna ukupholisa ulwelo, i-Advanced Microwave inikezela ngeenkonzo ze-OEM ukwenza ngokwezifiso uyilo lomthwalo we-coaxial kunye neendlela ezidibeneyo zokupholisa, iijometri zojongano lobushushu oluphuculweyo, kunye noqwalaselo lwezixhumi ezithile zesicelo. Iinkqubo zokulawula umgangatho ezingqongqo ziqinisekisa ukuba yonke iyunithi ihlangabezana neenkcukacha eziqinileyo zobushushu nombane, kunye novavanyo olupheleleyo oluqinisekisa ukusebenza kulo lonke uluhlu lobushushu lokusebenza oluchaziweyo. Iindlela zokwenza ngokwezifiso zifikelela ekuguquleni ukulinganiswa kwamandla kwizakhiwo ezithile zolawulo lobushushu, ukukhetha iintlobo zezixhumi ezenza ngcono ukusebenza kwe-RF kunye neemfuno zojongano lobushushu, kunye nokulungelelanisa ubukhulu bomzimba ukuhlangabezana neemfuno zofakelo ezithintelweyo kwindawo.
