Izixhumi ezingama-coaxial zingamadivayisi axhumanisa umhlaba wonke, kodwa futhi zinemikhawulo ethile. Okunye kwalokhu ukuphatha amandla, okuwukucatshangelwa okubalulekile ezinhlelweni eziningi zezixhumi ze-SMA. Izixhumi ze-SMA ziza ngezinhlobonhlobo eziningi, okuhlanganisa okujwayelekile, ukunemba, ukunemba okudlulele-, nezixhumi ezikhethekile{3}} ze-SMA ezihlosiwe ze-voltage ephezulu nezinye izinhlelo zokusebenza. Nakuba ukuhlukahluka kwezixhumi ze-SMA kusho ukuthi ukuthola leyo ehlangabezana nemingcele yobuchwepheshe kulula, kufanele kuqashelwe ukuthi amandla okubamba amandla alezi zixhumi awafani ngempela.
Kwezinye izimo, amandla okubamba amandla esixhumi se-SMA awakho ohlwini lwedatha. Lokhu kungenzeka kungenxa yokuthi isixhumi esinikeziwe se-SMA singadizayinelwa ukuthi sihlangane nohlu lwezintambo ezingama-coaxial, lapho amandla okubamba amandla esixhumi edlula awekhebuli yamakhoaxial. Okunye okungenzeka ukuthi ukuphatha amandla e-SMA kuncike ebangeni lefrikhwensi kanye nendlela yokukhweza. Ngokuvamile, kuzixhumi eziningi kanye nezingxenye/amadivayisi e-RF, ukuphatha amandla kuwumsebenzi wokuvama. Amadivayisi amaningi e-RF angakwazi ukuphatha amandla amancane kumafrikhwensi aphezulu ngenxa yokulahleka okukhuphukile kumafrikhwensi aphezulu.

Esinye sezizathu eziyinhloko zokuphathwa kwamandla okulinganiselwe ukuthi ukulahlekelwa kukagesi kuholela ekuguqulweni kwamandla kagesi ekushiseni, futhi ukusebenza kahle kokushisa okuphezulu kubangela ukuthi izinto zengxenye zishise kakhulu. Isikhala se-dielectric phakathi kwamakhondaktha aphakathi nendawo nangaphandle wesixhumi se-SMA ngokuvamile siyi-polymer enezinga lokushisa elilinganiselwe elingaphansi kuka-200 degrees Celsius (imvamisa engu-165 degrees Celsius). Yingakho amandla alinganiselwe ngokuvamile eyinombolo ethile yama-watts ngaphakathi kwebanga lefrikhwensi elishiwo ezingeni lokushisa eliphakeme kakhulu. Kukhona amandla aphezulu-noma anwetshiwe{6}okuhlukile kwe-SMA okunamandla okungadlula amandla okubamba amandla ezinye izixhumi ze-SMA ezivela kumkhiqizi ofanayo. Ngenxa yokuthi lezi zilinganiso nezindlela ziyahlukahluka kumkhiqizi ngamunye, kungase kudingeke ukucatshangelwa ngokucophelela ukuze kuqinisekiswe ukuthi isixhumi se-SMA esinamandla afanelekile siyakhethwa.
Isibonelo, isixhumi se-SMA esilinganiselwe ngo-12 GHz kuphela singase sibe namandla okubamba amandla aphezulu kunesixhumi se-SMA esilinganiselwe ngo-26.5 GHz. Kodwa-ke, i-26.5 GHz SMA ingase ibe namandla okuphatha amandla aphezulu ku-12 GHz, hhayi nje ngobuningi bayo. Ngenxa yokuthi izixhumi ze-SMA zisebenza kumafrikhwensi angaphezu kuka-30 GHz, ezinye zinemvamisa yokusebenza ephezulu engu-8 GHz kuphela, lokhu kungeza ubunkimbinkimbi obengeziwe lapho kuqhathaniswa ukuphathwa kwamandla kwezixhumi ze-SMA.

Izixhumi ezijwayelekile ze-SMA zefrikhwensi zingase zibe namandla okubamba amandla amagagasi aqhubekayo (CW) angu-100W emazingeni okushisa asukela ku-~100℃kuya ku-125 degree. Izixhumi ze-Precision SMA ezisebenza ku-26.5 GHz noma 30+ GHz zingakwazi kuphela ukuphatha amandla aphakathi kuka-50℃no-75℃. Ezinye izixhumi ze-SMA zinamandla okubamba adlula ama-watts angu-200, kodwa kuye ngomkhiqizi, ububanzi bazo bokuvama bokusebenza bungase bukhawulelwe ku-18 GHz noma ngisho no-12 GHz. Abanye abakhiqizi bangase bafake ohlwini ukuphathwa kwamandla okuphezulu ngezinga lokushaya kwenhliziyo kanye nomjikelezo womsebenzi esikhundleni sezinga lokubamba amandla e-CW, noma baklelise kanye nezinga lokubamba amandla e-CW.
